maxquad: The MAXQUAD Test Function

Description Usage Arguments Details Value References Examples

Description

Lemarechal's MAXQUAD optimization test function.

Usage

1
maxquad(n, m)

Arguments

n

number of variables of the generated test function.

m

number of functions to compete for the maximum.

Details

MAXQUAD actually is a family of minimax functions, parametrized by the number n of variables and the number m of functions whose maximum it is.

Value

Returns a list with components fn the generated test function of n variables, and gr the corresponding (analytical) gradient function.
