Breadth-first search, with loop detection
binaryMinSearch :: (Int -> Bool) -> Int -> Int -> Maybe Int Source #
Find the lowest value where the predicate is satisfied within the given bounds.
exponentialMinSearch :: (Int -> Bool) -> Int -> Maybe Int Source #
Find the lowest value where the predicate is satisfied above a given bound.
