Abstract
Lemke paths are often used in the solution of nonlinear programming pr oblems. We investigate a number of properties of Lemke paths, motivate d by the d-step conjecture for linear programming. Some negative resul ts are presented, including families of Lemke paths, for which the len gth of the shortest grows exponentially, joining pairs of vertices of a sequence of polytopes.
