Algorithm for solving system of nonlinear equations

  1. Feb 25, 2007 #1
    I'm trying to find an algorithm to solve a 4 variable system of nonlinear equations.. the variables are named w,x,y,z and a,b,c,d are constants:

    a = x - y + z
    b = w + x
    c = y * z
    d = x * y / w


    Can anyone offer any advice? Much appreciated...

    Gröbner basis algorithms could be used to, for example, eliminate all but one variable.
