The OPTLSO Procedure

Iteration Log

The iteration log provides detailed information about the progress of the OPTLSO procedure. The log appears by default or if LOGLEVEL=1. The iteration log provides the following information:

Iteration

Displays the number of completed genetic algorithm iterations.

Best Objective

Displays the best objective found at each iteration with respect to the current setting of the FEASTOL= option. Note: This column is included only for single-objective optimization.

Nondom

Displays the number of nondominated solutions in the current Pareto-optimal set. Note: This column is included only for multiobjective optimization.

Progress

Displays a numerical indication of the progress being made from one iteration to the next. For a description of how this value is computed, see the section Multiobjective Optimization. Note: This column is included only for multiobjective optimization.

Infeasibility

Displays the aggregate constraint violation of the current best point.

Evals

Displays the cumulative number of function evaluations.

Time

Displays the time needed to achieve current best solution.
