If you want to put together a five minute presentation on this, that would be great - the more the merrier. Meanwhile, if you want to exhaustively test a variant implementation: testdata=: 'abcd'{~4 4 4 4#:4^4 That's 256 distinct cases, and $ mm"1/~ testdata 256 256 2 That's an exhaustive test of the algorithm. So let's say you had two other implementations: mma and mmb (mma"1/~ -: mm"1/~) testdata 1 (mmb"1/~ -: mm"1/~) testdata 0 mma would be an equivalent implementation, while mmb is not.
