These are based on an implicit triangulation of the ambient space and pivoting in and out of the triangles. A slight modification of the pivoting algorithm allows us to derive a direct search method. Introduction to some frame-based direct search routines. Host: DDMA Data Sciences Summer School - Katharine Chartrand
