Stopping Conditions for the Pattern Search

This section describes the criteria for stopping the pattern search algorithm. These criteria are listed in the Stopping criteria section of the Pattern Search Tool, as shown in the following figure.

The algorithm stops when any of the following conditions occurs:

• The mesh size is less than Mesh tolerance.
• The number of iterations performed by the algorithm reaches the value of Max iteration.
• The total number of objective function evaluations performed by the algorithm reaches the value of Max function evaluations.
• The distance between the point found at one successful poll and the point found at the next successful poll is less than X tolerance.
• The change in the objective function from one successful poll to the next successful poll is less than Function tolerance.

The Bind tolerance option, which is used to identify active constraints for constrained problems, is not used as a stopping criterion.
