testFunOptimization {RCEIM}

1D test problem for RCEIM

Description

An one-dimension problem for testing optimization methods.

This function was created for demonstrating the RCEIM package. It has the form:

f(x) = exp(-((x - 2)^2)) + 0.9 * exp(-((x + 2)^2)) + 0.5 * sin(8*x) + 0.25 * cos(2*x)

Usage

testFunOptimization(x)

Arguments

x

The point where the function is computed.

Value

The value of the function at x.
