lp_probe(+Handle, +Objective, -Cost)
Invoke external solver using a temporary objective function.
- Handle
- Handle to existing solver state
- Objective
- Temporary objective function
- Cost
- Value of solution
Description
Similar to lp_solve/2, but optimize for a different objective function
rather than the one that was specified during solver setup. After the call
to this predicate, the original objective function is restored for the
external solver. However, any constraints collected and the eplex values
for the problem variables from the temporary objective function (obtainable
from lp_var_get/4) are retained.
Fail Conditions
External solver was unable to find a solution.
Exceptions
- (eplex_suboptimal)
- Solution was found, but is possibly suboptimal
- (eplex_unbounded)
- Problem is unbounded, no solution values
- (eplex_unknown)
- Result is unknown (infeasible or unbounded)
- (eplex_abort)
- External solver aborted for some reason
