Good guess. I'm developing a heuristic for the multivariate gcd over Z in Singular. And I must admit not having thought enough about the advantages of a statistical analysis. Its transparency beats SA and NN. Now I'm working on the statistical approach. At the moment, I'm trying to define the prob

Hello folks! Thank you, Michael, for introducing me. To me it seems sensible, that a fast gcd implementation should consist of a bunch of algorithms and a heuristic, that chooses one of them in dependence of the input. Currently I'm working on the heuristic. I'm thinking about letting the comput
