Hi, glpsol crashed by an assertion on my windows when executing. May be an interesting case for you guys. Output is as follow: GLPSOL: GLPK LP/MIP Solver, v4.55 Parameter(s) specified in the command line: --cover --clique --gomory --mir -m D:\src\atm-psc\psc\GLPK\model.mod -d D:\tmp\MRT\glpk\Network_MTRnet\model.dat -d D:\tmp\MRT\glpk\Network_MTRnet\3007000_ifu.dat Reading model section from D:\src\atm-psc\psc\GLPK\model.mod... 53 lines were read Reading data section from D:\tmp\MRT\glpk\Network_MTRnet\model.dat... 2876 lines were read Reading data section from D:\tmp\MRT\glpk\Network_MTRnet \3007000_ifu.dat... 1112 lines were read Generating z_constraint...
