摘要

This paper presents a global image space method for addressing a class of nonconvex programming problems (CNPP). By utilizing equivalent conversion and a two-phase linear relaxation technique, the CNPP can be transformed into a relaxed linear program problem. On the basis of the branch-and-bound framework, a global image space algorithm is designed for addressing the CNPP. By analyzing the computational complexity of this algorithm, we estimate the maximum number of iterations in the worst-case scenario. Finally, numerical experimental results are presented to indicate that this method is practicable and effective.
