The selection operator in genetic algorithm was improved. Finally, the improved algorithm was tested with AVIRIS image data. The maximum likelihood classification method was implemented to classify the selected optimal band combinations. The classification results illustrate that the total classification ...
The apparatus of Generalized Nets (GN) is applied here to a description of a selection operator, which is one of the basic genetic algorithm operators. The GN model presented here describes roulette wheel selection. The resulting GN model could be considered as a separate module, but it can ...
However, when we’re using this method as a GA operator, we don’t want to choose just one individual.Instead, we want to select a subset of the population for reproduction. In this sense, the algorithm below presents the complete procedure for the Tournament Selection.For this algorithm, i...
highlighting their advantages and challenges. In “Service broker policy problem” section, we have explained cloud computing service broker policy problem. “Problem encoding for genetic algorithm” section, we explain how we can
Finally, the mutation operator with the probability of 0.033 performs random modification to refine the solutions. As shown in Algorithm 1, the process evolves until a maximum number of generations, in this case 20, is reached. The NSL-features dataset were reduced to 19 at the end of the ...
This paper introduces a modified version of a genetic algorithm with aggressive mutation (GAAM), one of the genetic algorithms (GAs) used for feature selec
Genetic Algorithms The handling of selection pressure in the context of Genetic Algorithms mainly depends on the choice of the selection operator and the replacement scheme [Michaliwicz, 1996]. ’Generational replacement’, for example, replaces the entire population by the next one, whereas ’eliti...
operator i.e. it has a subprocess. It is necessary for the subprocess to deliver a performance vector. This performance vector is used by the underlying Genetic Algorithm. Have a look at the subprocess of this operator. TheSplit Validationoperator has been used there which itself is ...
The reinforcement learning-based mutation operator selection results in a higher number of test-passing variants, but does not exhibit a noticeable improvement in the number of bugs patched in comparison with the baseline, uniform random selection. While reinforcement learning has been previously shown ...
