Singular Manual: tInitialFormParMax

| #### D.13.6.27 tInitialFormParMax Procedure from library `tropical.lib` (see tropical_lib). Usage: tInitialFormParMax(f,w); f a polynomial, w an integer vector Assume: f is a polynomial in Q(t)[x_1,...,x_n] and w=(w_1,...,w_2) Return: poly, the t-initialform of f(t,x) w.r.t. (-1,w) evaluated at t=1 Note: the t-initialform are the terms with MAXIMAL weighted order w.r.t. (1,w) Example:
