optim.functions         optim.functions: A collection of standard
                        optimization functions along with a standard
                        interface to call and sample those functions.
sample.func             Unified function sampling interface.
samplingf               The sampling functions take (n, k) where n is
                        the number of samples and k is the number of
                        dimensions. The sampling functions should
                        return samples in a 0-1 hypercube.
                        sampling.func <- function(n, k)
