Solver Square Comparison: Considers all models.

Date / Time: 09/02/07 12:02:37


Solver comparison utility.

Compares all solver return outcomes (for example optimal, locally optimal, infeasible, unbounded, fail) of one solver with all return outcomes of another solver. Interrupt denotes resource or iteration limit has been reached. Solver CPLEX-SIMPLEX is represented on the left (rows) and solver CPLEX-BARRIER on top (columns). See the solver return definitions for return codes.

Models having trace data only in one trace file are listed in the "no data" column of the other.
