The SearchMethod syntax for PATTERNSEARCH has changed for Genetic Algorithm and Direct Search Toolbox 2.0.2 (R2006b). The method for storing linear and bound constraints and passing them to a search function has changed, resulting in faster processing and more efficient use of memory.

As a result, a warning message occurs for calls using the old syntax. To convert MATLAB files written using the old syntax to the new syntax, use the attached utility, searchConversion.m.
