nomad.jl's Issues

SubproblemManager

It crashed Julia. What does this mean?

Warning: SubproblemManager::clear() called on non-empty SubproblemManager

Source in C++ code:
https://github.com/bbopt/nomad/blob/cb3bb3543b14d9eb8aee270e9ef3b80a67f7708c/src/Algos/SubproblemManager.cpp#L117

Relationship between the granularity and the min_mesh_size of a NomadProblem

I would like to know if there is a relationship between the granularity and the min_mesh_size of a NomadProblem. I am currently trying to increase the granularity of real variables, but if I do so, should I also change the mesh size min_mesh_size?

NOMAD_jll has .so libraries instead of .dylib on FreeBSD

Add support for linear equality constraints

@salomonl

[documentation] SOLAR and STYRENE

SOLAR and STYRENE are now precompiled with Yggdrasil.
We should add a documentation page to explain how to use them with NOMAD.jl.

How to add minimum mesh size?

How to specify minimum mesh size in nomad.jl

NOMAD v4.4.0

There is a new version of NOMAD available as of January 2024: v4.4.0
https://www.gerad.ca/en/software/nomad/
Are there plans to upgrade NOMAD.jl to use this latest version of NOMAD?

Another error during NOMAD tests

J'obtiens ce problème lors de l'installation de NOMAD.jl sur la grille de calcul.
Si tu arrives à faire marcher NOMAD sur cette machine, ton script d'installation sera bien robuste.
Y a jamais rien qui marche par défaut dessus...

Add documentation about NOMAD executable

We should add documentation about how to use the NOMAD binary directly with NOMAD_jll. It could avoid some issues with libraries.

Remove Union{Nothing, Int} in the interface

Release 2.3.0

@salomonl
Do you want to update some files with the new version of NOMAD 4.2 ?
I would like to do a new release of NOMAD.jl with the new NOMAD_jll.

NOMAD segfaults on Manjaro Linux when Julia is started with "-t n" with n>1

Firstly, thanks for making this great optimizer available to Julia users!

I have an expensive objective function that takes about 20 seconds to evaluate with threading enabled in Julia. When I try to optimize with NOMAD on Manjaro Linux, starting Julia with -t2 -t3, etc., on my 8-core machine, I get the following error (-t1 works fine, though slowly):

I'm using NOMAD.jl v. 2.1.0.

Actually, from looking at the information my objective function writes out, it looks like the segfault is occurring in the objective function, presumably when the first Threads.@threads statement is encountered. But, as I noted previously, this error doesn't occur on my Windows machine, where I'm using 8 threads.

Thanks very much for your work on this! I'm running FreeBSD 13, and have clang 11.

Can't easily modify the nomad options from the NomadProblem constructor

I was fiddling with NomadProblem to try to set the max_time attribute of the NomadOption object to a certain value. It seems there is no easy way to do so. I tried to do it this way:

using NOMAD

parameters = [1.0, 2.0]

bb_output(parameters::AbstractVector{Float64}) = 0

function obj(v::AbstractVector{Float64})
    return true, true, bb_output(v)
end

nomad = NomadProblem(
               length(parameters),
               1,
               ["OBJ"],
               obj;
               input_types = ["R", "R"],
               granularity = [0.0, 0.0],
               lower_bound = [0.0, 0.0],
               upper_bound = [10.0, 10.0],
           )

options = NOMAD.NomadOptions(display_all_eval=true, display_infeasible=true, display_unsuccessful=true)

# This line fails because NomadProblem is an immutable struct
nomad.options = options

but NomadProblem is immutable. Is there a way to allow the user to specify some options? For example, we could change the inner constructor of NomadProblem to allow the user to pass the options he wants to change.

Parallel evaluation of the black-box

As discussed with @salomonl , it would be great to be able to evaluate in parallel the black-box function.

Use surrogate models

As discussed with @salomonl , it would be great to be able to specify a surrogate model.

How to use biobjective function in NOMAD.jl

In the user guide of NOMAD they said that NOMAD will be able to handle biobjective function also. Is it possible in our NOMAD.jl also?

How to use NOMAD with a function that depends on both the parameters to be optimized (x) and fixed parameters (p)?

Hi, I would really appreciate an example on this. Thanks.

`max_time` as an integer

Usually in Julia, the time() is a real number. Is there any specific reason why the max_time in NomadOption is fixed as an integer here, L.69?

Trouble installing

When I try to Pkg.add("NOMAD"), I get the following error. Might you know what's going on?

Getting Inexact Errors from NOMAD.jl when tuning Integer and Boolean variables

I sometimes obtain the following error when using integer and boolean inputs. From my perspective, it seems to happen randomly, but I am not sure. I will sometimes rerun NOMAD.jl and I won't get an error. Here is a recent stacktrace:

ERROR: LoadError: InexactError: Bool(1.00000000000003)                                                         [29/1822]Stacktrace:                                                                                                               [1] Bool                                                                                                                  @ ./float.jl:106 [inlined]                                                                                            [2] convert                                                                                                               @ ./number.jl:7 [inlined]                                                                                             [3] set_default!(parameter::AlgorithmicParameter{Bool, BinaryRange{Bool}}, new_value::Float64)

To fix the issue, I had to do a convert(Bool, round(Int64, value)).

Any ideas? I am curious why it seems to happen arbitrarily.

NOMAD exception

I get sometimes this exception:

NOMAD exception (report to developper):
NOMAD::Exception thrown (/workspace/srcdir/nomad/src/Param/PbParameters.cpp, 174) Invalid Parameter. Check: LOWER_BOUND is equal to UPPER_BOUND at index 2. Value =   0       
terminate called after throwing an instance of 'NOMAD_4_3::Exception'
  what():  NOMAD::Exception thrown (/workspace/srcdir/nomad/src/Algos/../Cache/CacheBase.hpp, 165) Cannot get instance. A non-virtual object derived from CacheBase must be instantiated first. For example, call CacheSet::setInstance() ONCE before calling CacheBase::getInstance()

If I restart Julia and try again it works. Any idea?

Additional finding: It seams to happen always if I did create a plot with PyPlot.jl BEFORE calling NOMAD.

Update the interface to support NOMAD4 options

As recommended by Christophe and Viviane, we should use the trick of the Python interface for passing the options.
I just need to recompile NOMAD with Yggdrasil when you give me the green light @salomonl.

Can't follow README or tutorial

The instructions in the README appear to be outdated. So does the tutorial. A simple up-to-date example with a constraint or two and installation instructions would be very useful. I looked in the NOMAD4 branch, but no success there either :-(.
