Abstract:

In order to better solve the quadratically constrained quadratic programming problem(QCQP), an adaptive linearized relaxation technique based on the framework of the branch and bound algorithm is proposed in this paper, which theoretically proved that this new delimitation technique is considerable for solving (QCQP). The branch operation in this paper adopts the conditional dichotomy to facilitate effective division of the rectangle; the reduction technique is used to delete some regions that do not contain the global optimal solution to speed up the convergence of the algorithm. Finally, the numerical results show that the proposed algorithm in this paper is effective and feasible.

Key words: quadratically constrained quadratic programming, global optimization, branch and bound, adaptive linearized relaxation technique, conditional dichotomy
