Termination. In the nature we don’t have (yet) a point that the process stops. In many cases an algorithm that runs forever is useless. We should try to find the correct time for terminating the whole process. That time may be after the results are good and/or before

The search for a good solution in a genetic algorithm context is the search for particular binary strings. Biological chromosomes cross over one another when two gametes meet to form a zygote similar to the process of crossover in genetic algorithms.

Genetic Algorithm & Ziegler-Nichols Tuning Criteria. Tuning methods for PID controllers are very important for the process industries. Traditional methods such as Ziegler-Nichols method often do not provide adequate tuning. Genetic Algorithm (GA) as anPID.

Genetic algorithms (GA) are search algorithms that mimic the process of natural evolution, where each individual is a candidate solution: individuals are generally “raw data” (in whatever encoding format has been defined). Genetic programming (GP) is considered a special case of GA, where each individual is a computer program (not just “raw data”).

In genetic algorithms and evolutionary computation, crossover, also called recombination, is a genetic operator used to combine the genetic information of two parents to generate new offspring. It is one way to stochastically generate new solutions from an existing population, and analogous to the crossover that happens during sexual reproduction in biology.
