Re: [Help-glpk] MIP Solvers (i.e CBC, CPLEX, GLPK, GUROBI, LPSOLVE, SCIPC, SCIPL, SCIPS and XPRESS) Benchmark

Hello Noli,

you are right that the GMPL interpreter has a value on its own.

Cf.
http://en.wikibooks.org/wiki/GLPK/Mixing_GLPK_with_other_solver_packages

Unfortunately the interfaces between GLPK-GMPL and other solvers tend
to be one time efforts without further maintenance.

Best regards

Xypron
