Abstract: A homotopy algorithm was used to solve unconstrained nonconvex programming. We construct fixed point homotopy equation for KT equation, and some results for homotopy pathway were obtained. It was also proved that homotopy algorithm can’t converge to a local maximum when proper homotopy equation was chosen.

Key words: unconstrained programming, homotopy algorithm, KT point
