When the algorithm nears or crosses the hyperplane theta=1, an "end game" phase is begun to compute the solution x(bar) satisfying p(a,theta,x(bar))=f(x(bar))=0. This note compares several end game strategies, including the one implemented in the normal flow code FIXPNF in the homotopy software package HOMPACK.application/postscriptenIn CopyrightTechnical reportTR-95-04http://eprints.cs.vt.edu/archive/00000419/01/TR-95-04.ps
