QR Code ISO/IEC18004 Reader In VS .NET
Using Barcode Control SDK for .NET Control to generate, create, read, scan barcode image in Visual Studio .NET applications.
Elitism refers to the process of ensuring that the best individuals of the current population survive to the next generation The best individuals are copied to the new population without being mutated The more individuals that survive to the next generation, the less the diversity of the new population

Hall of Fame
Recognize Quick Response Code In .NET Framework
Using Barcode recognizer for .NET Control to read, scan read, scan image in Visual Studio .NET applications.
The hall of fame is a selection scheme similar to the list of best players of an arcade game For each generation, the best individual is selected to be inserted into the hall of fame The hall of fame will therefore contain an archive of the best individuals found from the rst generation The hall of fame can be used as a parent pool for the crossover operator, or, at the last generation, the best individual is selected as the best one in the hall of fame

Reproduction is the process of producing o spring from selected parents by applying crossover and/or mutation operators Crossover is the process of creating one or more new individuals through the combination of genetic material randomly selected from two or more parents If selection focuses on the most- t individuals, the selection pressure may cause premature convergence due to reduced diversity of the new populations Mutation is the process of randomly changing the values of genes in a chromosome The main objective of mutation is to introduce new genetic material into the population, thereby increasing genetic diversity Mutation should be applied with care not to distort the good genetic material in highly t individuals For this reason, mutation is usually applied at a low probability Alternatively, the mutation probability can be made proportional to the tness of individuals: the less t the individual, the more it is mutated To promote exploration in the rst generations, the mutation probability can be initialized to a large value, which is then reduced over time to allow for

exploitation during the nal generations Reproduction can be applied with replacement, in which case newly generated individuals replace parent individuals only if the tness of the new o spring is better than that of the corresponding parents Since crossover and mutation operators are representation and EC paradigm dependent, the di erent implementations of these operators are covered in chapters that follow

Stopping Conditions

The evolutionary operators are iteratively applied in an EA until a stopping condition is satis ed The simplest stopping condition is to limit the number of generations that the EA is allowed to execute, or alternatively, a limit is placed on the number of tness function evaluations This limit should not be too small, otherwise the EA will not have su cient time to explore the search space In addition to a limit on execution time, a convergence criterion is usually used to detect if the population has converged Convergence is loosely de ned as the event when the population becomes stagnant In other words, when there is no genotypic or phenotypic change in the population The following convergence criteria can be used: Terminate when no improvement is observed over a number of consecutive generations This can be detected by monitoring the tness of the best individual If there is no signi cant improvement over a given time window, the EA can be stopped Alternatively, if the solution is not satisfactory, mechanisms can be applied to increase diversity in order to force further exploration For example, the mutation probability and mutational step sizes can be increased Terminate when there is no change in the population If, over a number of consecutive generations, the average change in genotypic information is too small, the EA can be stopped Terminate when an acceptable solution has been found If x (t) represents the optimum of the objective function, then if the best individual, xi , is such that f (xi ) |f (x) |, an acceptable solution is found; is the error threshold If is too large, solutions may be bad Too small values of may cause the EA never to terminate if a time limit is not imposed Terminate when the objective function slope is approximately zero, as de ned in equation (1616) of 16
