In later versions of GLPK, you need to use the iocp (integer optimization control parameter) structure to set these parameters.  I don’t know when it was introduced, and it’s possible that your version doesn’t have this control structure.  Look through “glpk.h” and if you see the iocp structure you should use that.


Use the “glp_init_iocp” routine to get an iocp structure.  Then set the parameters, and use “glp_intopt” to call the MIP procedure, which takes the iocp as a parameter.

I'm writing a model with a lot of binary variable. I can resolve it very quickly with glpsol using options --intopt --cuts .Without these options I didn't see the end, subproblems was growing  again after one hour. My problem is to find these options in the java api. GlpkSolver.LPX_K_USECUTS and GlpkSolver.LPX_INTOPT doesn't exist
Im using API 4.9 and can't find api 4.10
