The use of arithmetic to determine the chameneos compliments may be prohibited by the shootout rules. Although the benchmark does not address the issue, the C# code, which was written by Isaac Gouy (one of the main shootout administrators) contains these comments before its complement code: // don't use arithmetic // use if-else or switch/case or pattern-match
If I recall correctly, Gouy's C# code has served as a sort of supplement for other benchmarks; rather than fully describe the benchmark, they'll say something like "implement it like this C# program." However, I do note that the current Python entry uses arithmetic. That might have been allowed only because Python doesn't allow enums.

But I was inspired by your improvement to use Int# instead of data Color, and I posted a version that seems faster than the winning one that was submitted. http://www.haskell.org/hawiki/ChameneosEntry It still has to box the Int# to put it into the MVar channels. But the fastest complement is now (3# -# a -# b) and "if (other ==# faded)" is faster than the previous "case other of Faded -> ; _ ->". At least on OS X / G4. Also, thanks for cleaning up the SumFile code. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
