search for: equilibria

Dear R experts: I searched cran (and r-help) for "nash equilibrium" and "game" but nothing stuck out. has someone written a numerical nash optimizer for two players? player a has choices x1,x2,x3,... and cares about (maximizes) pa(x1,x2,x3,...,y1,y2,y3) player b has choices y1,y2,y3,..., and cares about (maximizes) pb(x1,x2,x3,...,y1,y2,y3) I can tune it to my problem, but

Is there an r package out there that solves for pure strategy* Nash equilibrium of a two-person game*? A search for Nash equilibrium in r provides a link to the *GNE* package which solves for the Generalized Nash equilibrium. But what I would like to solve is a pure strategy Nash equilibrium.

It has been continued by his students, primarily Ted Turocy. In Gambit, great care is...
