The NEOS Server offers SCIP for the solution of mixed-integer
linear and nonlinear programming problems in
CPLEX extended MPS format, in
CPLEX-LP format, in
ZIMPL format, or in
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.
OSIL and ZIMPL formats allow input of a general nonlinear MIP while extended MPS
format allows input of a quadratically constrained MIP.

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.
