Population::SelectionOperations::GaSelectTournament Class Reference

GaSelectTorunament selection is similar to GaSelectRouletteWheel selection. For one place in result set it performs multiple roulette wheel selection before it chooses only one chromosome with best fitness value among selected. This increases probability of selection of chromosome with better fitness value. This selection use GaSelectTorunamentParams class for parameters. More...

Detailed Description

GaSelectTorunament selection is similar to GaSelectRouletteWheel selection. For one place in result set it performs multiple roulette wheel selection before it chooses only one chromosome with best fitness value among selected. This increases probability of selection of chromosome with better fitness value. This selection use GaSelectTorunamentParams class for parameters.

This class has no built-in synchronizator, so LOCK_OBJECT and LOCK_THIS_OBJECT macros cannot be used with instances of this class. Because this genetic operation is stateless all public method are thread-safe.
