为了解决有约束的基于共轭梯度二次规划算法的多次迭代问题,结合共轭梯度算法和有效集策略,提出了一个新的算法模型,通过对变量的截取(使用Polak Bibiere 公式)来避免重新开始共轭梯度算法,在大规模的弹性接触问题中,大量的结果表明了这个算法的有效性。 |

Abstract: |
In order to solve constrained multiple iteration problem based on conjugate gradient for quadratic programming algorithm, by combining conjugate gradient algorithm and effective set strategy, this paper proposes a new algorithm model by truncating variables to avoid restarting conjugate gradient algorithm (by using Polak Bibiere formula). In large scale elastic contact problems, a lot of results show that this algorithm is effective. |
