## Solver Square Comparison: Considers all models.

 Date / Time: 09/27/02 10:16:11

Solver comparison utility.

Compares all solver return outcomes (for example optimal, infeasible, unbounded, interrupt, fail) of one solver with all return outcomes of another solver. Interrupt denotes resource or iteration limit has been reached. Solver BARON default is represented on the left (rows) and solver BARON op4 on top (columns). See the solver return definitions for return codes.

### Solver Resource Times

• Models for each solver pair outcome. Listed are the solver resource times in seconds, as well as the ratio of resource times for the two solvers if both solved optimally.
• Also listed are the objective values using both solvers. The better solution found is listed in boldface. A solution is considered better, if the relative objective function difference is greater than 1.00E-05.
• Solver resource time ratios for a particular model are listed only if one solver has resource greater than 5.00E-02.
