scip

The NEOS Server offers SCIP for the solution of mixed-integer second order cone problems in CPLEX extended MPS or in CPLEX LP format.

SCIP is a framework for Constraint Integer Programming oriented towards the needs of Mathematical Programming experts who want to have total control of the solution process and access detailed information. SCIP can also be used as pure MIP solver or as framework for branch-cut-and-price.

SCIP can be linked with a number of LP solvers and with the nonlinear solver IPOPT. See these benchmarks for the relative performance of SCIP.

Source and documentation are available from the SCIP Homepage

This solver was implemented by Hans Mittelmann and executes in 64-bit at

Using the NEOS Server for SCIP

The user must submit a mixed-integer programming problem in one of the formats given above. If non-standard parameter settings are required, the user may also submit changes from this default parameter file. Only the line(s) should be submitted in which a parameter is changed from default such as limits/solutions = 1 if SCIP should stop when the first feasible solution has been found (only with full presolve). When submitting via e-mail or XML-RPC delete empty tokens!

The administrator of SCIP reserves the right to keep and use problem instances submitted through NEOS for testing and debugging purposes.
