Question
The coefficients of a "Randomized" polynomials are too big for my purposes
Use R ::= Q[x,y,z]; Randomized(x-yz); 2129104241yz - 2703411994x -------------------------------
What can I do?
Answer
This function will produce a randomized polynomial with "small" random coefficients
Define MyRandomized(F, Range)
Return Sum([ Rand(-Range,Range)*T | T In Support(F)]);
EndDefine;
MyRandomized(x-yz, 4); 2yz + 6x -------------------------------
