#34 Adds support for random effects via the pipe operator. While going through the example in the PR I noticed that operations that are written as `x2|m` were then printed as `m:x2` because formulai…

I was surprised to learn that the implementation of `core::ops::{Add, Mul}` (keywords: addition, multiplication) is not automatically (and exclusively) commutative. This is often not a problem for cas…

A graded-commutative ring is a mildly noncommutative ring in which `x*y = (-1)**(x.deg()*y.deg())*y*x` for the right notion of degree. This ticket aims to implement ideals of graded-commutative ring…

Aaron pointed out a nice paper at http://arxiv.org/abs/1002.3180 that shouldn't be too bad to implement as a non-commutative factoring algorithm.
Original issue for #6225: http://code.google.com/p/sy…

?- X = s(1), X = s(X).
false.
?- X = s(X), X = s(1).

How can I change this for min, max ,or gcd LCM and xor etc...
I can change in combine function but what are function i should change
You can explain by taking any example like for gcd or range xor e…
