A POLYNOMIAL PREDICTOR-CORRECTOR INTERIOR-POINT ALGORITHM FOR CONVEX QUADRATIC PROGRAMMING 总被引:2,自引:0,他引:2
This article presents a polynomial predictor-corrector interior-point algorithm for convex quadratic programming based on a modified predictor-corrector interior-point algorithm. In this algorithm, there is only one corrector step after each predictor step, where Step 2 is a predictor step and Step 4 is a corrector step in the algorithm. In the algorithm, the predictor step decreases the dual gap as much as possible in a wider neighborhood of the central path and the corrector step draws iteration points back to a narrower neighborhood and make a reduction for the dual gap. It is shown that the algorithm has O(n~(1/2)L) iteration complexity which is the best result for convex quadratic programming so far. 相似文献

基于粒子群算法的非线性二层规划问题的求解算法 总被引:3,自引:0,他引:3
粒子群算法(Particle Swarm Optimization,PSO)是一种新兴的优化技术,其思想来源于人工生命和演化计算理论。PSO通过粒子追随自己找到的最好解和整个群的最好解来完成优化。该算法简单易实现,可调参数少,已得到了广泛研究和应用。本文根据该算法能够有效的求出非凸数学规划全局最优解的特点,对非线性二层规划的上下层问题求解,并根据二层规划的特点,给出了求解非线性二层规划问题全局最优解的有效算法。数值计算结果表明该算法有效。 相似文献
