findMax :: (Fractional a, Ord a) => (a -> Bool) -> a Source
findMin :: (Fractional a, Ord a) => (a -> Bool) -> a Source
Given an upward-closed predicate on an ordered Fractional type, find the smallest value satisfying the predicate.
findMinFrom :: (Fractional a, Ord a) => a -> a -> (a -> Bool) -> a Source
Given an upward-closed predicate on an ordered Fractional type,
find the smallest value satisfying the predicate. Starts at the
specified point with the specified stepsize, performs an exponential
search out from there until it finds an interval bracketing the
change-point of the predicate, and then performs a bisection search
to isolate the change point. Note that infinitely-divisible domains
such as Rational cannot be searched by this function because it does
not terminate until it reaches a point where further subdivision of the
interval has no effect.
