Editing Selection (evolutionary algorithm) (section)

=== Boltzmann selection ===
In Boltzmann selection, a continuously varying temperature controls the rate of selection according to a preset schedule. The temperature starts out high, which means that the selection pressure is low. The temperature is gradually lowered, which gradually increases the selection pressure, thereby allowing the GA to narrow in more closely to the best part of the search space while maintaining the appropriate degree of diversity.<ref>{{Cite book|last=Sivanandam, S.
