individuals
Mutation
-maximal number of GA generations
-high similarity of individuals in the population
-the best individual is repeated maximal times
-GA has reached global optimum or the best GA solution is good enough (according to some criterion)
-limited time of the GA run….
The combination of few stopping criterions gives the best results in practice...
-generation GA: all individuals from the population are replaced in each GA generation
-stationary GA: only one part of the population is replaced
-elitistic GA: elite individuals are directly passing in the next genaration, while the remaining individuals are replaced
-GA implementation has numerous paremeters: selection, crossover, mutation rates, population size, ….
-there is no unique combination of GA parameters that guarantees sucessful GA implementation for all problems
-the parameter values may fixed in advance or they can change during the GA run
-fixed parameter change
-adaptive parameter change
