Simple use of the Watchmaker framework (https://github.com/dwdyer/watchmaker) to optimize the sphere function in N dimension. The sphere function is just (x_1*x_1, ..., x_n*x_n) with a single global minimum at (0, ..., 0).

haskell is pretty cool
import Data.List
rightTriangles = [(a,b,c) | c <- [1 .. ], b <- [1..c], a <- [1..b], a^2 + b^2 == c^2]
{--
*Main> take 10 rightTriangles
[(3,4,5),(6,8,10),(5,12,13),(9,12,15),(8,15,17),(12,16,20),(15,20,25),(7,24,25),(10,24,26),(20,21,29)]
--}
