Singular Manual: completeReduction

| #### D.7.2.5 completeReduction Procedure from library `ainvar.lib` (see ainvar_lib). Usage: completeReduction(p,I[,q,n]); p poly, I ideal, [q monomial, n int] Return: a polynomial, the SAGBI reduction of the polynomial p with respect to I via the procedure 'reduction' as long as possible if n=1, a different algorithm is chosen which is sometimes faster (default: n=0; q and n can be given (or not) in any order) Note: help reduction; shows an explanation of SAGBI reduction Example:
    LIB "ainvar.lib";
    ring q=0,(x,y,z,u,v,w),dp;
    poly p=x2yz-x2v;
    ideal dom =x-w,u2w+1,yz-v;
    completeReduction(p,dom);
    ==> 2xyzw-yzw2-2xvw+vw2
    completeReduction(p,dom,w);
    ==> 0
