On solving the sum-of-ratios problem
Webrithm, sum-of ratios problem, guaranteed global optimality. 1 Introduction The sum-of-ratios problem, which is to minimize (maximize) a sum of several fractional func-tions subject to convex constraints, is a non-convex optimization problem that is di cult to solve by traditional optimization methods. The problem arises in many applications such as Web13 de mai. de 2014 · This paper presents a branch and bound algorithm for globally solving the sum of concave-convex ratios problem (P) over a compact convex set. Firstly, the problem (P) is converted to an equivalent problem (P1). Then, the initial nonconvex programming problem is reduced to a sequence of convex programming problems by …
