finding the weighted degree of a polynomial

Let p(x,y) be a polynomial in x,y expressed in its expanded form, i.e.
as a sum of terms as follows:

 p(x,y) = sum   c_ij x^i y^j

I want to find the (a,b)-weighted degree of this polynomial defined as

wdeg(p, {a,b}) = max (ai + bj)   with c_ij != 0

(where a and b are given fixed values)

help is welcome,
thanks
