We discuss a filter-based pattern search method for unconstrained
optimization in this paper. For the purpose to broaden the search
range we use both filter technique and frames, which are fragments
of grids, to provide a new criterion of iterate acceptance. The
convergence can be ensured under some conditions. The numerical
result shows that this method is practical and efficient.
