Summary

The module ProblemSimple contains a very simple optimization problem, which can be used to illustrate the optimization process. It contains a time delay, which allows to reduce the speed of evaluations. This can be used e.g. to show the convergence of an optimization algorithm in a presentation.

Options

The options are the number of discrete and continuous variables and an optional time delay for per evaluation.

Module Description

Computation of the Objective

The single objective function f is a quadratic function. More precisely, f is computed as the square of all continuous and discrete variables.

f(x) = sum_i(x_i²)

This function is also referred to as the sphere function.
