摘要: Warren M. Hirsch posed the conjecture which bears his name in a letter of 1957 to George B. Dantzig. Simply stated geometric terms, proposed that polytope dimension dwith n facets admits path at most (n−d) edges connecting any two vertices. context linear program d variables and constraints as requiring maximum (n− d) pivots — steps simplex algorithm— on shortest path, achieve an optimum. Over years theHirsch has attractedmuch research attention, been proved number special cases. This article contributes proof general bounded case.
