In this paper, non-convex global optimization problems with constraints are studied. By using the structures of filter and filled function, a generalized filter filled function algorithm based on gradient projection is presented and the theoretical properties and numerical results are obtained. The algorithm modifies the definition of the filled function and the application scope of the filter technique, which extends the local optimization technique and makes it one of effective methods to solve the global optimization problems with constraints.
