A filter-trust-region method for $$LC^1$$ unconstrained optimization and its global convergence. (English) Zbl 1164.65022
Summary: We present a filter-trust-region algorithm for solving $$LC^1$$ unconstrained optimization problems which uses the second Dini upper directional derivative. We establish the global convergence of the algorithm under reasonable assumptions.
