A Shamanskiĭ-like acceleration scheme for nonlinear equations at singular roots
1986
Mathematics of Computation
Preserved Fulltext
A variation of the Shamanskii method is used to obtain a superlinearly convergent method for a class of nonlinear equations having singular Fréchet derivative at the root. The cost of a superlinear step is one derivative evaluation and two function evaluations.
