Ali is right, GUSEK enable all cuts by default, see the options in
"View > Parameters" menu, field 1.|
Please use latest version of GLPK from http://winglpk.sourceforge.net (4.39).
Gusek use the same GLPK version - even it was buid with MingW.
If you wanna try, you can substitute the glpsol.exe binary in GUSEK main
folder by another version / build, it'll work (at least in latest versions).
GUSEK is just a IDE, GLPK is "the solver" =)

Another interesting thing is that, using EXACTLY the same parameters, the compilation of glpsol 4.9 I downloaded from http://winglpk.sourceforge.net/ is unable to get the gap below 4.6% (the optimum is 0%), whereas it seems to solve fairly easily in the GUSEK 0.2 Windows IDE. This is exactly the opposite to another problem I have also been working on, in which I used GUSEK for development only because it took around 5x longer to resolve in that program.It is probably because GUSEK uses a more recent version of GLPK than 4.9 and the newer versions implement cut generations. Try enabling / disabling cut generation, it may lead to significant differences in the computation time. Good luck, Ali
