Abstract

In this paper, we propose a gradient-type method for solving a quadratic separable knapsack problem, which is simpler than the existing methods and competitive in practice. The algorithm uses a smooth approximation of the dual function of the knapsack problem. Partial convergence and complexity results of the algorithm are presented. Moreover, to demonstrate its efficiency, illustrative computational results are reported.
