Trying to calculate partition of a number using generating fuction with
memoization, like this:
{{{
#!/usr/bin/runhaskell
part'' :: Int - Integer
part'' = ( map part' [0..] !!)
part' :: Int - Integer
part' 0 = 1
part' 1 = 1
part' n =
sum $ map (\k -
let kk = fromInteger(k); k1 = floor(1/2*kk*(3*kk-1)); k2 =
floor(1/2*kk*(3*kk+1)) in
(-1)^(k+1) * ( (part (n-k1)) + (part (n-k2))) ) [1..toInteger(n)]
part n =
if n 0 then 0 else part'' n
main = print $ part 2
}}}
Then i watch how memory usage grows up to 2G (RES) and program stops:
