Optimizer Library C API
Once the problem has been loaded into the Xpress Optimizer, it can be written to an MPS file using the API call XPRSwriteprob():
XPRSwriteprob(prob, "myproblem", "");
This will save the current problem in prob in the MPS format to the file myproblem.mps.
In order to create the binary saved state file, you should add the call
XPRSsave(prob);
just before any call to XPRSmipoptimize(). The XPRSsave() function will write to a file whose name is given by the name of the problem itself. This name can be changed using XPRSsetprobname(). If the problem name is "myproblem", then XPRSsave() will create a file called myproblem.svf.
Equivalent functions exist for the Java, .Net and VB APIs. Please refer to the appropriate reference manual.
