[Help-glpk] solve mps problem

[Spring]

Hi,

I'm using java to GLPK4.8 interface and I've created by using the function "writeMPS" (i.e. routine lpx_write_mps) an mps file that represent the problem I want to solve. I'm able to read and solve problem in mps format by using other solver (like COIN_OR cbc) but I'm not able to solve the problem in MPS format with GLPK because I've the following error:

 

lpx_read_mps: reading problem data from `info/optimizationFiles/F2cv_ProblemDescription.mps'...

lpx_read_mps: problem name not specified

lpx_read_mps: 9132 rows, 3740 columns, 299717 non-zeros

lpx_read_mps: 3740 integer columns, all of which are binary

lpx_read_mps: 168143 cards were read

spx_simplex: problem has no rows/columns

lpx_integer: problem is not of MIP class

 

What's the problem?

Thanks
