Abstract
In this paper, to compute the fixed point of selfmapping on general nonconvex sets, a modified constraint
shifting homotopy algorithm for perturbing simultaneously both equality constraints and inequality
constraints is proposed and the global convergence of the smooth homotopy pathways is proven under some
mild conditions. The advantage of the newly constructed homotopy is that the initial point needs to be only
in the shifted feasible set, not necessarily, an interior point in the original feasible set, and hence it is more
convenient to be implemented than the existing results. Some numerical examples are also given to show
its feasibility and effectiveness.
