[Bug-glpk] Problem to solve MIP problem

[Cedric[FR]]

Hi,

I have this problem:

When I use this routine (lpx_intopt(glpkProbPtr)), my problem is solved
normally.

But, when I use this routine (glp_intopt(glpkProbPtr,&glpkParamMipPtr)), my
problem doesn't solve the problem.

The error message is: glp_intopt: optimal basis to initial LP relaxation not
provided

I don't unsderstand. None parameters are passed at glpkParamMipPtr.

Just, I initialize glpkParamMipPtr with glp_init_iocp(&glpkParamMipPtr);

why?

Thanks

Cédric
