Webbcies, "simplicial methods". A crucial part of Scarf's method was an algorithm for exchanging (pivoting) vertices of simplices, using combinatorial arguments as in Lemke (1965). Hansen (1968) furnished an improvement of Scarf's algorithm by giving an efficient and compact pivoting procedure. Kuhn (1968, 1969) also discovered the same WebbThese notes were used by the second author in a course on simplicial homotopy theory given at the CRM in February 2008 in preparation for the advanced courses on simplicial methods in higher categories that followed.
