It looks fun. "We are not afraid that students would try to tune their work to the similarity tester. We reckon if they can do that they can also do the exercise."
I used a tool called MOSS from Alex Aiken for detecting plagiarism in programming class, but it was not open source. I guess I need a more efficient algorithm for finding the "moved" code. Currently it is recursive and very slow. I guess techniques used in "common subexpression elimination" may help. -- Yin On Sat, Sep 15, 2012 at 10:33 AM, Hendrik Boom <hend...@topoi.pooq.com> wrote: > On Fri, Sep 14, 2012 at 04:34:21AM +0800, Yin Wang wrote: >> Hello, >> >> I'm developing a tool for "diffing" program by parse trees and not >> text.
