B  
brent [Max1D]  brent f a b uses Bent's method to return (x, f x) where x is
the best approximation to a maximum point of f on the interval
[a,b] .

brent [Min1D]  brent f a b uses Bent's method to return (x, f x) where x is
the best approximation to a minimum point of f on the interval
[a,b] .

G  
golden_search [Max1D]  golden_search f a b c returns (x, f x) where x is an
approximaion of a maximum point of f inside the interval
[a,c] .

golden_search [Min1D]  golden_search f a b c returns (x, f x) where x is an
approximaion of a minimum point of f inside the interval
[a,c] .
