Global optimization algorithms for bound constrained problems

Cutting angle method - a tool for constrained global optimization

Cutting angle method (CAM) is a deterministic global optimization technique applicable to Lipschitz functions f : Rn → R. The method builds a sequence of piecewise linear lower approximations to the objective function f . The sequence of solutions to these relaxed problems converges to the global minimum of f . This article adapts CAM to the case of linear constraints on the feasible domain. We...

αBB: A global optimization method for general constrained nonconvex problems

A branch and bound global optimization method, BB, for general continuous optimization problems involving nonconvexities in the objective function and/or constraints is presented. The nonconvexities are categorized as being either of special structure or generic. A convex relaxation of the original nonconvex problem is obtained by (i) replacing all nonconvex terms of special structure (i.e. bil...

A New Quasi-Filled Function Method for Constrained Global Optimization

In this paper, a class of new auxiliary function with one parameter on constrained problem for escaping the current local minimizer of global optimization problem is proposed. Firstly, we give a definition of the quasifilled function for constrained problem and under some mild assumptions, we prove the proposed auxiliary function is a quasi-filled function. Then, a new algorithm is presented ac...
