pycutest's Issues

Symbol not found: __intel_fast_memcpy

I tried to run the code "p = pycutest.import_problem('ROSENBR')", it raised an error:

It seems that there is something wrong with __intel_fast_memcpy. Does anyone know how to fix it? Thanks in advance.

Cannot make it work in Ubuntu 18.10 and Anaconda Python

Hi,

I tried to installed it both using pip and manually but when trying to load any problem I get the error:

Python 3.7.1 (default, Dec 14 2018, 19:28:38)

Problem with PyCUTEst.find_problems()

Describe the bug
When I tried to find problems as the tutorial using
probs = pycutest.find_problems(constraints='unconstrained', userN=True), I got the following error message.

Traceback (most recent call last):
File "", line 1, in
File "/local/scratch/szhao89/optim/lib/python3.8/site-packages/pycutest/sifdecode_extras.py", line 294, in find_problems

'origin': cfDict['origin'][cfString[5].upper()],
KeyError: 'S'

However, other functions work. For example, I can run
p = pycutest.import_problem('ROSENBR').

Information about your installation:
I just followed the instruction to install cutest and compile it.

Thanks for your help!

Clean up documentation

The main page with all the interface functions is hard to navigate - needs cleaning up (including links between list of available functions and definition, or entries on the LHS index sidebar, etc).

Needs some work because doc generation was automated with Sphinx autodoc extension (not sure how to modify). Alternatively, migrate everything into the rst files directly (not as nice, but at least it's fully configurable).

Release of memory

Hi, it seems that the pycutest still occupy much CPU memory and will not release if we didn't terminate the python program.

problems_name = ["HS7", "HS6", "HS56", "HS48", "HS60"]
tracemalloc.start()
for name in problems_name:
    prob = pycutest.import_problem(name, drop_fixed_variables=True)
    for i in range(2000):
        x = prob.x0
        g = prob.objcons(x)

    del prob
    gc.collect()

    snapshot = tracemalloc.take_snapshot()
    display_top(snapshot)

It is reported that the CPU memory is increasing...
Looking forward to your help, thanks!

import_problem

Hi, when i use pycutest.import_prolem(), i get the following error:

from ._pycutestitf import *
ImportError: dlopen(/Users/username/pycutest_cache/pycutest_cache_holder/BT9/_pycutestitf.cpython-38-darwin.so, 0x0002): symbol not found in flat namespace 'cutest_cdh'

May i ask how to solve it? Thanks very much!

When I am compiling any c++ program i am getting this error.Please tell me how to remove this.

ld: warning: dylib (/opt/homebrew/Cellar/gcc/10.2.0_4/lib/gcc/10/libstdc++.dylib) was built for newer macOS version (11.2) than being linked (11.0)

I want to specify the dimension of the unconstrained optimization problem, how do I set that?

1.How to set M? Do I need to keep M?

2.The second question is, why can't I find the minimum using Newton's method? Is it because the problem is more complicated?

Add access to gradient only

Is your feature request related to a problem? Please describe
Currently, the gradient for an unconstrained problem can only be accessed along with either the objective or Hessian:

_, g = prob.obj(x, gradient = True)
g, _ = prob.gradhess(x)

A similar issue is true with constrained problems.

Describe the solution you'd like
Ideally, I'd like to have access to the gradient alone, i.e.,

g = prob.grad(x)

Describe alternatives you've considered
This isn't a blocking change for my work since accessing the gradient through the objective is sufficiently cheap, but this approach is aesthetically unpleasing.

Inconsistency in problem dimensions between description and problem

Describe the bug

There are two ways to determine the dimensions of a CUTest problem using pycutest: The problem properties and the problem itself. In some instances, these ways disagree.

To Reproduce

The following snippet

import pycutest

print("pycutest version:", pycutest.__version__)

name = "HATFLDBNE"

props = pycutest.problem_properties(name)

print(props)

print(f"Props: n = {props['n']}, m = {props['m']}")

problem = pycutest.import_problem(name)

print(problem)
print(f"Problem: n = {problem.n}, m = {problem.m}")

yields the following output:

pycutest version: 1.7.0
{'objective': 'none', 'constraints': 'other', 'regular': True, 'degree': 2, 'origin': 'academic', 'internal': False, 'n': 4, 'm': 0}
Props: n = 4, m = 0
CUTEst problem HATFLDBNE (default params) with 4 variables and 4 constraints
Problem: n = 4, m = 4

As can be seen, there is some ambiguity as to whether the problem has constraints (is m = 0 or m = 4?). It is possible to evaluate the constraints at the provided x0, so I guess m = 4 is correct?

Information about your installation:

Linux
Python 3.12.3
PyCUTEst Version: 1.7.0

Check system path

In build_interface.import_problem(), check that cache is in the Python path. Easiest way would be to add an ImportError catch to lines 341-342:
return CUTEstProblem(__import__('%s.%s' % (CACHE_SUBFOLDER, problemDir), globals(), locals(), [str(problemDir)]), drop_fixed_variables=drop_fixed_variables)

If this throws an ImportError, just try to import CACHE_SUBFOLDER - an ImportError here indicates the Python path can't see it. This will hopefully avoid issues when using IDEs, etc.

Conversion of an array with ndim > 0 to a scalar is deprecated and will error in future

The latest version of NumPy has a deprecation warning:

pycutest/problem_class.py:673: DeprecationWarning: Conversion of an array with ndim > 0 to a scalar is deprecated, and will error in future. Ensure you extract a single element from your array before performing this operation. (Deprecated NumPy 1.25.)

  ci = float(ci)  # convert from 1x1 NumPy array to float

We should fix this sooner rather than later or there will be inevitable breakage.

Suggested upstream fix is to simply extract the first element (cf https://numpy.org/doc/stable/release/1.25.0-notes.html#deprecations):

float(a)  # better: a[0] to get the numpy.float or a.item()

Unclosed file warnings when calling sifdecode

Currently on Python 3 we get the following warnings whenever sifdecode is called:

test_sifdecode_extras.py:21: ResourceWarning: unclosed file <_io.TextIOWrapper name=3 encoding='UTF-8'>
build_interface.py:333: ResourceWarning: unclosed file <_io.TextIOWrapper name=3 encoding='UTF-8'>

I've traced it to the p = subprocess.Popen(...) lines in sifdecode_extras.py and build_interface.py, however doing the sensible thing and using with subprocess.Popen(...) as p: fixes the warnings on Python 3 but breaks sifdecode on Python 2:
https://travis-ci.org/github/jfowkes/pycutest/jobs/673033735

Any thoughts on this? I'm confused.

Add new CUTEst routines for the John function

CUTEst 2.2 added routines for the (Fritz) John function, defined as

$$ \mathcal{J}(x,\lambda_0,\lambda) = \lambda_0 f(x) + \langle \lambda, c(x) \rangle $$

(for more details please see https://en.wikipedia.org/wiki/Fritz_John_conditions)

The following new routines have been added to CUTEst 2.2:

cdimohp
cdimsg
cdhj
cshj
cshj_threaded
chjprod
chjprod_threaded
cisgrp
cohprods
cohprodsp
cohprods_threaded
timings_threaded

We should add support for these in PyCUTEst as appropriate.

GCC error on ARM-based architecture

Bug description

After installing PyCUTEst as detailed in the documentation, I cannot compile CUTEst problems via PyCUTEst. The tests of the Fortran source files (both sifdecode and cutest) succeed, but not the import_problem function.

I ran the following code:

# Example: building problem
import pycutest

# Find unconstrained, variable-dimension problems
probs = pycutest.find_problems(constraints='U', userN=True)
print(sorted(probs)[:5])

# Properties of problem ROSENBR
print(pycuttest.problem_properties('ROSENBR'))

# Print parameters for problem ARGLALE
pycutest.print_available_sif_params('ARGLALE')

# Build this problem with N=100, M=200
problem = pycutest.import_problem('ARGLALE', sifParams={'N':100, 'M':200})
print(problem)

I got the following result:

['ARGLINA', 'ARGLINB', 'ARGLINC', 'ARGTRIGLS', 'ARWHEAD']

Switch to `pyproject.toml`

As pointed out by @ragonneau, setup.py is being mostly replaced with pyproject.toml:
https://packaging.python.org/en/latest/guides/modernize-setup-py-project/#modernize-setup-py-project

We should therefore switch PyCUTEst over to the modern pyproject.toml way of installing things, especially as Python 12 no longer ships with setuptools installed by default like it used to.

It may still be necessary to retain a very basic setup.py so that we can read in the version.

Use of pycutest with virtual environments

A very nice package for using CUTEst, thanks a lot for the work.

Issue

I can get the package to work, but I find the ${PYCUTEST_CACHE} environment variable a pain point
when working with multiple environments that use pycutest. It makes sense that this would be separate as you might want to manage a global CUTEst function cache but having to manually add it to the python path is a pain, especially when trying to replicate an install on someone else's computer.

Proposed solution(s)

Add a fallback if the environment variable is not defined in the sites-packages/pycutest/ folder.
Add the ${PYCUTEST_CACHE} environment variable to the python path when pycutest is imported.

These changes seem to superficially have the benefit of being backwards compatible.

I'm happy to do a PR with either or both of those things if you're interested but thought I'd bring it up first.

Hessian for constrained problems

As mentioned in the JOSS pull request: the error message when using hess (or sphess) and not passing in a Lagrange multiplier vector v for a constrained problem is not very friendly:

Traceback (most recent call last):
  File "/Users/jari/s_matrix.py", line 20, in <module>
    H = prob.sphess(x0)  # Sparse Hessian (COO)
  File "/usr/local/lib/python3.9/site-packages/pycutest/problem_class.py", line 667, in sphess
    self.check_input_v(v)
  File "/usr/local/lib/python3.9/site-packages/pycutest/problem_class.py", line 225, in check_input_v
    elif v.shape != (self.m,):
AttributeError: 'NoneType' object has no attribute 'shape'

My suggestion here is:

For all problems, prob.hess(x), prob.ihess(x), prob.sphess(x) and prob.isphess(x) all return the Hessian of the objective
For constrained problems, prob.hess(x, v) and prob.sphess(x, v) return the Hessian of the Lagrangian

@jfowkes - it seems that your instinct was that hess(x) returns the Hessian of the objective even for constrained problems, hence the issue.

Potential issue with problem import and objective function call

Hello!

First I would sincerely thank you for developing such a great interface, however, while using pyCUTEst, I noticed some issue related to problem import and objective function call for some problem instances.

Namely, problems 'WAYSEA1NE' and 'HIMMELBA' triggers AttributeError: module 'pycutest_cache_holder.WAYSEA1NE' has no attribute 'info' when I import them via pycutest.import_problem().

Also, for some problems, the function value and gradient are evaluated to 0.0, array([0.0, 0.0]), respectively, at the initial point for that problem, via calling problem.obj(problem.x0, gradient=True). I also tried obtaining the function value for a few points close to the initial point, which also gives the function value and gradient being all 0. I'm wondering if this is an issue related to my usage or the interface itself.

Here's the list of problems with the issue mentioned above: ['BEALENE','BOXBOD','BROWNBSNE','CLUSTER', 'DANIWOOD','DANWOOD','DENSCHNCNE','ELATVIDUNE', 'EXPFITNE','FBRAIN','FBRAINNE','GBRAIN','GOTTFR', 'HIMMELBC','HIMMELBD','HS1NE','HS8','HYPCIR', 'JENSMPNE','JUDGENE','MISRA1A','MISRA1B','MISRA1C', 'MISRA1D','POWELLBS','POWELLSQ','PRICE3NE', 'PRICE4NE','RSNBRNE','S308NE','SINVALNE','WAYSEA2NE']

I attached a pdf file illustrating the two issues I mentioned above.

I sincerely appreciate your time taking a look into my issue.

Best wishes,
Yihe

macOS CI runners have stopped working

Something changed when the macos-latest (macos-12) GitHub Actions runners got updated from version 20221204.1 to version 20221215.1 and we now get the error:

dyld[8848]: Library not loaded: '@rpath/libgcc_s.1.1.dylib'
Referenced from: '/usr/local/Cellar/gcc@11/11.3.0/lib/gcc/11/libgcc_s.1.dylib'
Reason: tried: '/usr/local/lib/libgcc_s.1.1.dylib' (no such file), '/usr/lib/libgcc_s.1.1.dylib' (no such file)

The main change seems to be an update from macOS 12.6.1 to macOS 12.6.2 (the macOS-11 runner images have the same issue).

How to find problems with equality constraints only?

Hi everyone, I am a new user to pycutest package. I used the function probs = pycutest.find_problems(constraints='equality') to find test problems with equality constraints only. I found 19 problems in total. However, as I typed the command probs.m, for all of them, the output is 0, which implies that all test problem I found have no constraints. I had no idea where I did wrong. Thank you for any suggestions.

RuntimeError: Could not find CUTEST installation - have CUTEST and MYARCH environment variables been set correctly?

Hi there, I met above error after installing cutest and pycutest. I hope to get some help on this! Thank you!

Here is more details:
I tried brew test cutest, brew test sifdecode, brew test mastsif, it all pass with no error reported.

The detailed error message:

RuntimeError: Could not find CUTEST installation - have CUTEST and MYARCH environment variables been set correctly?

I note that in the error message, the get_cutest_path() function in File "/Users/zhengy/opt/miniconda3/envs/env3.10/lib/python3.10/site-packages/pycutest/system_paths.py" raise this error, so I went into it. Here is the relavent codes: (I'm using Mac)

def get_cutest_path():
    if sys.platform == 'darwin':  # Mac
        # First try environment variables, otherwise use default homebrew location
        if 'CUTEST' in os.environ and 'MYARCH' in os.environ:
            cutest_path = os.path.join(os.environ['CUTEST'], 'objects', os.environ['MYARCH'], 'double', 'libcutest.a')
            if os.path.isfile(cutest_path):
                return cutest_path
        homebrew_path = os.path.join('usr', 'local', 'opt', 'cutest', 'lib', 'libcutest.a')  # /usr/local/opt/cutest/lib/libcutest.a
        if os.path.isfile(homebrew_path):
            return homebrew_path
        else:
            raise RuntimeError('Could not find CUTEST installation - have CUTEST and MYARCH environment variables been set correctly?')

I'm confused bc I notices that "/usr/local/opt/cutest/lib/libcutest.a" is a valid file on my end.

$ pwd
/usr/local/opt/cutest/lib
$ ls
libcutest.a		libcutest_double.a	libcutest_single.a
libcutest.dylib		libcutest_double.dylib	libcutest_single.dylib

Thus, I don't know why it raises the RuntimeError and how to fix it. From my understanding, homebrew_path = os.path.join('usr', 'local', 'opt', 'cutest', 'lib', 'libcutest.a') is a valid file and should be returned.
Please let me know if I need to provide further information. Thank you so much for the help!

Local gfortran linker path warning

At the moment we have in install_scripts.py on line 94 a hardcoded '/usr/local/gfortran/lib/' path for Mac, however this is causing an ugly linker warning to show up if not used:

ld: warning: directory not found for option '-L/usr/local/gfortran/lib/'

I'm thinking that instead we could add an optional environment variable that gets picked up in system_paths.py if it is defined? That way we could avoid the potentially confusing warning.

Facing error when attempting to run the given example

Hello, please kindly help me resolve this error I got when calling "pycutest.import_problem( " " )" which is essential for getting the problems

KIndly see the screen-shot below

module 'pycutest_cache_holder.X' has no attribute 'setup'

Regrettably PyCUTEst v1.5.0 breaks existing cached problems (we had to fix a memory leak).

When upgrading to PyCUTEst v1.5.0, please clear out your cache by deleting the $PYCUTEST_CACHE/pycutest_cache_holder directory:

rm -r $PYCUTEST_CACHE/pycutest_cache_holder/

Failure to do so will result in errors of the form:

>>> pycutest.import_problem('ROSENBR')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/jari/Code/pycutest/pycutest/build_interface.py", line 345, in import_problem

  File "/home/jari/Code/pycutest/pycutest/problem_class.py", line 52, in __new__
    module.info = module.setup() # setup CUTEst problem
AttributeError: module 'pycutest_cache_holder.ROSENBR' has no attribute 'setup'

How to release RAM

When I test an unconstrained optimization algorithm ，I found that reuse pycutest.import_problem will lead the RAM increase fastly.

import pycutest

uncon = pycutest.find_problems(constraints='unconstrained', userN=True)
for prob in uncon:
    p = pycutest.import_problem(prob)

Only exit Python can release RAM

Setuptools not installed by default

When installing PyCUTEst via pip install pycutest, the required dependency setuptools is not installed alongside. This is important because setuptools is no longer shipped by default with Python starting from Python 3.12.

I see it appears in requirements.txt, but I suppose setup.py should be modified to add setuptools somewhere.

Cheers,
Tom.

Add missing sparse routines (sobj, sgrad)

The official CUTEst MATLAB interface has the sparse routines:

Tool    CUTEst function   Purpose
--------------------------------------------------------------------------
sobj    uofg / cofsg      Evaluate objective function value
                          and its sparse gradient if requested
sgrad   ugr / cisgr       Evaluate objective function or
                          constraint gradient as a sparse vector

These are the sparse equivalents of our existing obj and grad routines.

We should probably implement these in a similar way as done there:

Trying to debug this, I found that this error occurs at line 319 of build_interface.py:

return CUTEstProblem(__import__('%s.%s' % (CACHE_SUBFOLDER, problemDir), globals(), locals(), [str(problemDir)]), drop_fixed_variables=drop_fixed_variables)

Do you know by any chance why these warnings and error may be occurring and how it can be fixed?

I installed CUTEst and PyCUTEst using brew and pip following your instructions and am using Mac OS X 10.13.6 and CUTEst 2.0.0. Thanks in advance!

Support for ARM-based Mac

Does this interface support ARM-based computers? I didn't read anything like that in the README, so hopefully I'm not missing something obvious. CUTEst itself seems to be working properly at first glance, although I couldn't do much testing.

I get the following output, when I try to run the example for building problems available at https://jfowkes.github.io/pycutest/_build/html/building.html#building-problems:

PyCUTEst v1.5.0 breaks existing cached problems

Regrettably PyCUTEst v1.5.0 breaks existing cached problems (we had to fix a memory leak).

When upgrading to PyCUTEst v1.5.0, please clear out your cache by deleting the $PYCUTEST_CACHE/pycutest_cache_holder directory:

rm -r $PYCUTEST_CACHE/pycutest_cache_holder/

Failure to do so will result in errors of the form:

Question: Optimal values for testfunctions

Is there a way to get the optimal values for the testfunctions? Also is there a way to get the parameters where the optimal value is attained?

Problem compilation issue when pycutest.importing_problem(string) is called.

When trying to import a problem

probname = "ROSENBR"
ct = pycutest.import_problem(probname, quiet=False)

the following exception gets thrown. It looks like something is wrong with the resulting .so module file. The module file exists after the exception was thrown.

Problem name: ROSENBR

Add citation information

Is your feature request related to a problem? Please describe
n/a

Describe the solution you'd like
We should add citation information to the README and documentation (beyond just the badge), to make it easy for everyone to see the citation info.

(I'm quite busy with other things right now, so putting this here mostly as a reminder to myself!)

Better handling of incompatible Fortran compilers

A common error amongst our users is when CUTEst is compiled with a different compiler to that which the Python environment is using (see e.g. #2, #7, #14).

By default our automatic shell script installer should pick up the shell default gfortran:

$ gofrtran --version

but for some users this is not the same as that picked up by their Python interpreter:

python3 -c 'import subprocess; subprocess.call(["gfortran", "--version"])’

which is what PyCUTEst uses by default.

This situation then leads to the dreaded and very user-unfriendly error:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File ".../python3.6/site-packages/pycutest/build_interface.py", line 347, in import_problem
   drop_fixed_variables=drop_fixed_variables)
 File ".../python3.6/site-packages/pycutest/problem_class.py", line 52, in __new__
   [module.info](http://module.info/) = module.setup() # setup CUTEst problem
 File ".../CUTEST/pycutest_cache/pycutest_cache_holder/ARGLALE_M200_N100/__init__.py", line 69, in setup
   (n, m)=_pycutestitf.dims()
Exception: Failed to open data file

The question is, can we handle this error more gracefully than at present?

Should we change the shell script to automatically detect the python gfortran?

error when Installing on Linux

Hi,

I was following the documentation "Installing CUTEst on Linux", and I ran the command

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/jfowkes/pycutest/master/.install_cutest.sh)"

And I got the error below:

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/jfowkes/pycutest/master/.install_cutest.sh)"

Could you please give some advice? Thanks a lot!

By the way, gfortran -v gives me gcc version 6.2.0 (GCC).

Compilation in parallel on macOS does not work

Describe the bug
Although things work smoothly on Ubuntu, the compilation of problems cannot be done in parallel on macOS.

To Reproduce
I tried to run the following code:

import logging

import pycutest
from joblib import Parallel, delayed


def get_logger(name):
    logger = logging.getLogger(__name__)
    if len(logger.handlers) == 0:
        logger.setLevel(logging.INFO)

        # Attach a console handler (thread-safe).
        handler = logging.StreamHandler()
        handler.setFormatter(logging.Formatter('[%(levelname)-8s] %(message)s'))
        logger.addHandler(handler)
    return logger


@delayed
def load_problem(problem_name):
    logger = get_logger(__name__)
    logger.info(f'Loading {problem_name}')
    try:
        pycutest.import_problem(problem_name)
        logger.info(f'{problem_name} successfully loaded')
    except Exception as exc:
        logger.warning(f'{problem_name} failed to load: {exc}')


if __name__ == '__main__':
    problem_names = pycutest.find_problems(constraints='unconstrained', n=[1, 10])
    Parallel(n_jobs=-1)(load_problem(problem_name) for problem_name in problem_names[:5])

This code attempts to load five problems. I assume here that PYCUTEST_CACHE is set to a location where the problems have not already been compiled. I get the following output:

[INFO    ] Loading SISSER

Python Headers on Ubuntu

Hello,

I'm using the Ubntu system. After I followed the instructions to install cutest and pycutest, it gives me the following error message. Any help would be greatly appreciated.

An option or function to get all the problems compiled and saved, so that they do not need to be compiled on the fly

Hello, Jaroslav and Lindon (and anyone else who is maintaining PyCUTEst),

First of all, thank you very much for making CUTEst available under Python. It has been playing an essential role during our development of COBYQA @ragonneau . I know it takes a huge effort to make this happen.

Is your feature request related to a problem? Please describe

Sorry if I overlooked something and this feature is already available. Is there an option/function that allows us to get all the problems compiled and saved, so that they do not need to be compiled again later? This question is relevant for two reasons. First, some difficult problems take a significant amount of time and computing power to compile. Second, the compilation may fail (due to various reasons, e.g., limited resources, or some uncovered bug somewhere) from time to time. It would be great if all the problems can be prepared beforehand (for only once), and users never need to worry about the compilation when using these problems for testing.

Describe the solution you'd like

Make it possible to get all the problems compiled and saved, so that they do not need to be compiled a second time. Sure, some problems accept some options when being compiled (e.g., dimension). In that case, we may only compile the problem with the default option.

Describe alternatives you've considered

You may see my package MatCUTEst, which is the MATLAB counterpart of PyCUTEst (sure, CUTEst already provides a MATLAB interface; MatCUTEst makes it easier to use). When MatCUTEst is installed, all the problems will be compiled (it may take some time). After that, all problems are available via the function macup (an analog of pycutest.import_problem), which does nothing more than locate the compiled problem without doing any compilation. This saves enormous time during the testing.

In addition, I also made a compiled version of MatCUTEst, which can be used without any compilation (of course, if works only for limited combinations of OS and MATLAB). With MatCUTEst, it is easy to use CUTEst in GitHub Actions, particularly with GitHub hosted runners, which would be rather time/resource-consuming if problems need to be compiled on the fly. It would be great if the same can be done for PyCUTEst. Anyone who wants to use PyCUTEst in CI would benefit.

Thank you very much for your attention.

Best regards,
Zaikun

Issues with setting problem dimension

I'm currently not able to set the problem dimension in the sifParams option for some of the CUTEst problems. When trying to set N to be 500 for the SROSENBR problem, I receive the following error:

Traceback (most recent call last):
  File "main.py", line 35, in <module>
    problem = utils.CUTEstProblem(args.problem_name, args.N, args.print_sif, args.eps_f, args.eps_g)

    raise RuntimeError('SIFDECODE error: %s' % param_error)
RuntimeError: SIFDECODE error:  Failed setting N to 500

I've tried clearing the cache but it doesn't help. I've checked to make sure that this is an sifParams option using the print_available_sif_params function, which gives this:

Parameters available for problem SROSENBR:
N/2 = 5 (int, n = 10 original value)
N/2 = 25 (int, n = 50)
N/2 = 50 (int, n = 100)
N/2 = 250 (int, n = 500)
N/2 = 500 (int, n = 1000)
N/2 = 2500 (int, n = 5000) [default]
N/2 = 5000 (int, n = 10000)
End of parameters for problem SROSENBR

Could I get some help on where to start debugging this? Thanks in advance!

Error in using pycutest

Hi,

I follow the instruction in https://jfowkes.github.io/pycutest/_build/html/install.html to install cutest on Mac.
My mac version is Monterey 12.5. I use Pycharm with python 3.8 and gfortran 12.1

Then I run the tests in "Building Test Problem" of https://jfowkes.github.io/pycutest/_build/html/install.html
the first one "Find Problems", my output is fine

Pycutest with Knitro solver

Hello, please can you help me with the following issue:

Does the package support an interface to solve cutest problems with Knitro solver?

Thank you.

Migrate to GitHub Actions

As the free Travis CI is now deprecated and not running, we should switch our CI over to GitHub Actions. This should be relatively straightforward and largely a case of migrating the travis.yml file over to the GitHub Actions syntax.
