I am getting the following error when trying to run LEAP in the debug file. What does no memory error mean ?
Model has been successfully generated

glp_mpl_build_prob: row cost; constant term 646.803676576 ignored
glp_alloc: no memory available

1 Like That looks like GLPK is failing to solve due to running out of memory. GLPK cannot solve large problems. You may need to consider using CPLEX, which must be purchased separately from LEAP. For more help, please review the GLPK manuals: https://www.gnu.org/software/glpk/

Is there a guide setting LEAP to use CPLEX?
Also Is there a preferred CPLEX distributor?

As far as I know, IBM is the sole distributor of CPLEX.
Note that GAMS is NOT needed for using LEAP with OSEMOSYS.

Thanks for your help.
