Issues with setting problem dimension about pycutest HOT 2 CLOSED

Many thanks for reporting! This is a bug on our side: when we create CUTEst problem subfolders in the cache folder, we append the parameters (if there are any) to the folder name. Unfortunately, as N/2 is the parameter name for SROSENBR, we try to create the folder SROSENBR_N/2500 which is not a valid folder name as it contains the special character /.

Until we fix this, I suggest the following workaround: edit SROSENBR.SIF in your $MASTSIF folder so that the parameter you want is the only one that is unstarred (this will make it the default):

*   N/2 is half the number of variables

*IE N/2                 5              $-PARAMETER n = 10     original value
*IE N/2                 25             $-PARAMETER n = 50
*IE N/2                 50             $-PARAMETER n = 100
*IE N/2                 250            $-PARAMETER n = 500
*IE N/2                 500            $-PARAMETER n = 1000
 IE N/2                 2500           $-PARAMETER n = 5000
*IE N/2                 5000           $-PARAMETER n = 10000

For example, in the above N/2=2500 is the default. You can then call pycutest.import_problem('SROSENBR') and it will compile with the default parameter you just set.

@lindonroberts: any thoughts on how we could fix this? Linux does not allow / in folder names :(

from pycutest.

When we have parameters, the folder name is based on the problem plus the result of the function params_to_string() in build_interface.py. Modified to drop '/', and replace digits with test.

For example, now SROSENBR with sifParams={'N/2':250} is saved in cache folder "SROSENBR_Ntwo250".
