Genetic Algorithm and Direct Search Toolbox

Genetic Algorithm Options

This section describes the options for the genetic algorithm. There are two ways to specify options, depending on whether you are using the Genetic Algorithm Tool or calling the function ga at the command line:

• If you are using the Genetic Algorithm Tool (gatool), you specify the options by selecting an option from a drop-down list or by entering the value of the option in a text field. See Setting Options for the Genetic Algorithm.
• If you are calling ga from the command line, you specify the options by creating an options structure, using the function gaoptimset. See Setting Options at the Command Line. For example, to set PopulationSize to 50, enter

• options = gaoptimset(PopulationSize, 50)
  

You can identify an identify an option in one of two ways:

• By its label, as it appears in the Genetic Algorithm Tool
• By its field name in the options structure

For example:

• Population type refers to the label of the option in the Genetic Algorithm Tool.
• PopulationType refers to the corresponding field of the options structure.

The genetic algorithm options are divided into the following categories:

• Plot Options
• Population Options
• Fitness Scaling Options
• Selection Options
• Reproduction Options
• Mutation Options
• Crossover Options
• Migration Options
• Output Function Options
• Stopping Criteria Options
• Hybrid Function Option
• Vectorize Option
