Multivariate Polynomial Factoring Algorithm

[MrAl]

Hello,


I need one of these, hopefully in pseudo language of some sort.

Example:

Factor(a^2+2*a*b+b^2)

but there are going to be more variables than a and b and more terms
also.

I am going to update my Scientific calculator program and want to
add multivariate polynomial factoring to it also.


Thanks.
