Hello everybody!
I have a problem with the CPLEX "solution pool" feature, which fails writing its solutions into the solution pool or creating/finding the temporary solution-file.
This is my code:
option solver cplex;
problem Modell_A: ...;
option cplex_options 'poolstub masterpool poolcapacity 10 ';
solve Modell_A;
for {i in 1..Current.npool}
{
solution ("masterpool" & i & ".sol");
display _varname, _var;
}
And this my error message:
CPLEX
12.6.1.0: poolstub masterpool
poolcapacity 10
can't open masterpool1.sol
CPLEX
12.6.1.0: optimal integer solution; objective 5
1793 MIP simplex iterations
247 branch-and-bound nodes
No basis.
Wrote 0 solutions in solution pool.
Could not open "masterpool1.sol"
suffix npool OUT;
Do you have any hints?
Thanks,
Niko
