A monotone system of min-max-polynomial equations(min-max-MSPE) over the variablesX1,...,Xnhas forevery iexactly one equation of the form Xi= fi(X1,...,Xn) where eachfi(X1,...,Xn) is an expression built up from polynomialswith non-negative coefficients, minimum- and maximum-operators. Thequestion of computing least solutions of min-max-MSPEs arisesnaturally in the analysis of recursive stochastic games[5,6,14]. Min-max-MSPEs generalize MSPEs for which convergencespeed results of Newton's method are established in [11,3]. Wepresent the first methods for approximatively computing leastsolutions of min-max-MSPEs which converge at least linearly.Whereas the first one converges faster, a single step of the secondmethod is cheaper. Furthermore, we computee-optimal positional strategies for the player whowants to maximize the outcome in a recursive stochastic game.
