D.6.6.8 modSagbiAlg

Procedure from library classify_aeq.lib (see classify_aeq_lib).

Usage:
modSagbiAlg(I,i); I is an ideal, i an integer (optional).

Return:
ideal, a sagbi basis for I using modular methods.

Purpose:
Computes a sagbi basis for the ideal given by the generators in I using modular techniques.
If second argument is 0 then the result is not verified.

Example:
 
LIB "classify_aeq.lib";
ring R=0,t,ds;
ideal I=t8,t10+t13,t12+t15;
modSagbiAlg(I,0);
==> _[1]=t8
==> _[2]=t10+t13
==> _[3]=t12+t15
==> _[4]=t23-t29
==> _[5]=t27
modSagbiAlg(I);
==> _[1]=t8
==> _[2]=t10+t13
==> _[3]=t12+t15
==> _[4]=t23-t29
==> _[5]=t27
