摘要

Let X be a compact polyhedron that is homotopy equivalent to the figure-eight. This is a survey paper for the WYK algorithm which provides computations for the Nielsen number of self-maps of X. The WYK algorithm consists of three parts and each part was introduced separately by Wagner, Yi and Kim, and Kim. In this paper, we present the whole algorithm so that people can more easily use the algorithm.
