Re: [Help-glpk] solves for mixed-integer quadratic problems

[usa usa]

I prefer open source or free solvers.

Any help would be appreciated.

Many of the commercial solvers can handle convex MIQPs and MIQCPs (e.g. Gurobi, Cplex, Mosek, Xpress). Some of them can do also some (restricted) classes of non-convex problems. For general non-convex quadratic problems see e.g. Glomiqo/Antigone, or global MINLP solvers such as Baron.

Thanks for all your reply.

Can anybody recommand some effcient algorithms that can solve MIQCQP ?

It would be better if the algorithm has been implemented.

Any help would be appreciated.

Thanks

CLP is for continuous problems. I am not sure if CBC supports MIQPs or MIQCPs.

I have not used it myself.
