text: We study the existence of approximate pure Nash equilibria in weighted congestion
games and develop techniques to obtain approximate potential functions that prove
the existence of alpha-approximate pure Nash equilibria and the convergence of
alpha-improvement steps. Specifically, we show how to obtain upper bounds for
approximation factor alpha for a given class of cost functions. For example for
concave cost functions the factor is at most 3/2, for quadratic cost functions
it is at most 4/3, and for polynomial cost functions of maximal degree d it is
at at most d + 1. For games with two players we obtain tight bounds which are
as small as for example 1.054 in the case of quadratic cost functions.
