Performance Profile Summary

Date / Time: 06/28/07 20:57:36

Performance profiles for different objective value tolerances. The profile utility compares solver outcomes of any number of given solvers (up to 8) over a model test set. The tool is described in detail at http://www.gamsworld.eu/performance/pprofile.htm.

A solver is considered feasible or optimal, if it has the proper model and solver return codes and the relative objective value error is within n % of the best possible solution. If the best found objective value is 0, then the absolute objective value error is used.

The following relative objective value tolerances are used:

Only best objective value (i.e. 0 % of best solution found. Actual tolerance used is 1e-5 using relative error)
No objective value tolerance, i.e. we do not check if obj is best found (within Inf%).

Quality of Solution (within 0% wrt to best value)
