Hello, I am doing computations over the symbolic ring SR in order to (mostly) preserve the structure of my expressions (e.g., (x+y)*(z+w) should stay factored). Keeping the structure is important for later code generation purposes.
I also frequently want to know whether two expressions are the same, and in particular to build efficient dictionaries keyed by a canonical version of the expression for CSE. The expressions will always be multivariate integer polynomials. If p,q are two such expressions, does it suffice to use p.expand() as the canonical form? Is that the fast way?
