摘要
对一维搜索的二点二次插值法,利用Anderson-B j rck外推的思想提出了一个加速收敛算法,得出并证明了两条收敛性定理,且通过数值试验验证了该算法比二点二次插值法收敛速度快很多。
The paper discussed the Quaduatic Interpolation of One dimension search. According to the method of Anderson - Bjorck Extrapolation,it obtained an algorithm of accelerated Convergence and got the proof of the conclusion. Several numerical tests comfirm the fact that this algorithm is much faster than the Quaduatic Interpolation.
