Asynchronous parallel pattern search (APPS) is a practical method for many optimization engineering problems since it does not require gradient or approximate gradient information and can execute function evaluations in parallel over a heterogeneous and even fault-prone cluster computing environment. However, APPS was designed for unconstrained optimization while most engineering problems have bound constraints. We introduce several alternatives for incorporating bound constraints into APPS and present numerical results for various engineering problems.
