Efficient Method to Find A Root and/or Minima of A Multivariate Polynomial With Constraints on the Variables

65 Views Asked by At

I have a polynomial $P(x,y,z,...)$ which has integer coefficients and real roots. I want an efficient method that is guaranteed to find a root (I only need one), and if possible, one that finds a local minima, with each of the variables $\in [0,1]$.
