A language for computational topology

sigfpe makes a case for Haskell, using simple Haskell code to compute Betti numbers.

  1. Regarding Haskell, if not computational topology: Doug McIlroy has some papers using Haskell as a clean represenation for power series  (see also here) and enumerating strings of a regular language

  2. Ken,

    Actually, besides writing the homology code I've also written power series code and a tiny combinatorics library that makes use of it (the code for the latter seems to have become slightly garbled - I'll fix it).

    Here.

    Funnily enough I've also implemented regular expression code based on the Brzozowski derivative. There's something about Haskell that leads people towards implementing the same kinds of projects...
