Added to the repos - can you please provide your prefered optimization parameters to GHC ? e.g. a Makefile?

- phnguyen 15y agoHey ttsiodras, "ghc -O2 Main.hs" should be enough. I've updated the code a bit. It's now half F#'s execution time on my computer :)
- ttsiodras 15y agoExcellent. And committed - I will study your code, Haskell is next on my agenda :-)
- phnguyen 15y agoSo I updated my code to also print out debug. And Haskell now is almost 4 times faster than F# on my computer ;)
- ttsiodras 15y agoHmm... the scores you printed are not correct (look at the two board edges): C++: sh -c "time ./bin.release/score4 o53 y43 -debug" Depth 7, placing on 0, score:2 Depth 7, placing on 1, score:8 Depth 7, placing on 2, score:8 Depth 7, placing on 3, score:8 Depth 7, placing on 4, score:8 Depth 7, placing on 5, score:8 Depth 7, placing on 6, score:2 5 Your Haskell code: sh -c "time ./score4.bin o53 y43 -debug" Depth 7, placing on 0, score 0 Depth 7, placing on 1, score 8 Depth 7, placing on 2, score 8 Depth 7, placing on 3, score 8 Depth 7, placing on 4, score 8 Depth 7, placing on 5, score 8 Depth 7, placing on 6, score 0 5 I'll try to see why your code miscalculates on the two borders, but I don't speak Haskell so don't expect much :-)
- phnguyen 15y agoHi ttsiodras, thanks for poiting out :D. I looked at the code and figured out where it went wrong. I discussed my problem further on https://github.com/phuc/Score4-haskell/issues/1 https://github.com/phuc/Score4-haskell/issues/1. Btw I don't know whether Github notifies everytime I respond. I'm so inefficient at communicating, lol.
