Selection pressure, a probabilistic measure of a chromosome's likelihood of participation in the tournament based on the participant selection pool size, is easily adjusted by changing the tournament size, the reason is that if the tournament size is larger, weak individuals have a smaller chance to be selected, because, if a weak individual is selected to be in a tournament, there is a higher probability that a stronger individual is also in that tournament. Where did the concept of a (fantasy-style) "dungeon" originate? The tournament selection method may be described in pseudo code: Deterministic tournament selection selects the best individual (when p = 1) in any tournament. Software Engineering Stack Exchange is a question and answer site for professionals, academics, and students working within the systems development life cycle.

This was seen in 2010 when Northern Iowa (a No. Tournament selection involves running several "tournaments" among a few individuals (or "chromosomes") chosen at random from the population.The winner of each tournament (the one with the best fitness) is selected for crossover. It just guarantees that each individual has an equal chance of participating in the same number of tournaments. Instead if you do that it will put everyone in order from 1 to whatever number of players are in the tournament. To extend this, use another variable 'better'.
