Boltzmann Tournament Selection
Description
In the Boltzman tournament, the initial selection pressure is low. Therefore, every individual, whether low or high fitness value, has a chance to be selected. In the following generations, the selection pressure gradually increases. In other words, individuals with high fitness value are forced to be selected.
