You can use GLPSOL to generate the problem in CPLEX LP format and then feed that to another solver: http://en.wikibooks.org/wiki/GLPK/Interoperability http://en.wikibooks.org/wiki/GLPK/Interoperability#GLPSOL_usage http://en.wikibooks.org/wiki/GLPK/Interoperability#CPLEX.C2.A0LP_format The call is: $ glpsol --check --wlp model.lp --math model.mod GLPK can also tackle the same file: $ glpsol --lp model.lp If you encounter problems, you could also try bridging with the MPS free format. Described in the above links. You might also find something useful here, particularly if you are coding in C, Java, or similar: http://en.wikibooks.org/wiki/GLPK/Mixing_GLPK_with_other_solver_packages HTH, Robbie --- Robbie Morrison PhD student -- policy-oriented energy system simulation Technical University of Berlin (TU-Berlin), Germany University email (redirected) : morri...@iet.tu-berlin.de Webmail (preferred) : rob...@actrix.co.nz [from Webmail client] _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org https://lists.gnu.org/mailman/listinfo/help-glpk
