D.2.5.10 randomLast

Procedure from library random.lib (see random_lib).

Usage:

randomLast(b); b int

Return:

ideal = maxideal(1), but the last variable is exchanged by a random linear combination of all variables, with coefficients in the interval [-b,b].

Example:

LIB "random.lib";
ring  r = 0,(x,y,z),lp;
ideal i = randomLast(10);
i;
→ i[1]=x
→ i[2]=y
→ i[3]=-x+z
