Interesting program. You blog that it is too slow, so I took a look at your code. I expect you could speed it up substantially with a few changes to the data structures and so on. Some hints:
- Classes are going to be slower than functions and structures - Use fxvector for a vector of integers and the fx functions for operating on integers (this won't get you much, but is useful if you later switch to unsafe-fx, which is faster) - provide/contract can be faster than define/contract for recursion functions - Use Typed Racket to automatically and safely turn fx operations into faster unsafe-fx operations etc. HTH, N.
