One Step Secant Method Because the BFGS algorithm requires more storage and computation in each iteration than the conjugate gradient algorithms, there is need for a secant approximation with smaller storage and computation requirements. The one step secant (OSS) method is an attempt to bridge the ...

本期对Incremental Secant Method的收敛性进行一个深入讨论。在常规的Newton–Raphson方法中,切线刚度矩阵是在每次迭代时计算的,而改进的Newton–Raphson方法需要计算一次或在一定次数的迭代后计算。如前所述,…
