### solving a model with deferent solvers

Posted:

**Mon Jun 04, 2018 5:13 pm**Hello

I try to solve a model with deferent solver simultaneously. for example, with cplex, xpress, lindo.

My code is:

Scalar iter;

Parameter solution;

for(iter=1 to 1,

******************************************************

OPTION MIP=cplex;

SOLVE FCTP USING MIP MIN obj;

if (FCTP.modelstat<>%modelstat.Optimal%,

abort 'no feasible solution for FCTP');

solution=obj.l;

DISPLAY "cplex solution is", solution;

******************************************************

OPTION MIP=xpress;

SOLVE FCTP USING MIP MIN obj;

if (FCTP.modelstat<>%modelstat.Optimal%,

abort 'no feasible solution for FCTP');

solution=obj.l;

DISPLAY "xpress solution is", solution;

******************************************************

OPTION MIP=lindo;

SOLVE FCTP USING MIP MIN obj;

if (FCTP.modelstat<>%modelstat.Optimal%,

abort 'no feasible solution for FCTP');

solution=obj.l;

DISPLAY "lindo solution is", solution;

);

Do you know the better way to code it?

Best regards
