Introduction

The Optimize Tab is where you set up and run optimizations.

The controls on the Optimize Tab are arranged from top to bottom in the order in which you should use the controls. The sections below also follow this order, so you can read this page from top to bottom to learn the process of setting up and running optimization.

The Optimize Tab is shown below with its controls labeled. See the Appropriate section below for help on a particular control.

Algorithm Settings Table

The algorithm settings table is used to specify all parameters that affect the optimizer aside from the objective function and constraints. The settings that are displayed in this table change depending on which algorithm is selected in the Algorithm Menu. For help on a particular optimization algorithm's settings, see the help page for that algorithm.

Linking settings to problem parameters

Settings that require numerical values can be specified by directly entering the desired number into the settings table, or by entering a function of one or more of the following variables:

  • nVars = the number of independent variables (Rave determines this automatically based on the function that calculates the variable selected to serve as the objective
  • numberofequalities = the number of equality constraints
  • numberofinequalities = the number of inequality constraints (excluding upper/lower bounds on the independent variables
  • numberofbounds = the number of bound constraints (since in Rave each variable has an upper and a lower bound, this is always even)

The variable names must appear exactly as shown here (case sensitive).

If Something Breaks...

Unlike the other tabs, Rave saves the current state of the optimize tab when you switch to another tab, and restores it when you switch back to the optimize tab. This means that if something on the Optimize Tab breaks, simply switching tabs will not restore it to working order. The most common cause for this is if you are debugging an optimizer and you quit the optimizer from MATLAB's debug mode. This will cause the Stop button to not turn back into a Start button.

If this happens, you can completely reset the Optimize Tab by doing either of the following:

  • Click the "Rave" Logo that appears below the tabs. This will completely reset the tabs and will display the Manage tab.
  • Enter full screen mode by clicking the Fullscreen mode button or by right clicking an empty place on the workspace and selecting "Full Screen Mode" from the context menu.
