A genetic algorithm is a search technique that uses concepts from reproduction and natural selection to produce better solutions (children) from previous solutions (parents). Genetic algorithms are useful in a wide variety of applications requiring the optimization of a function, including some forms ...
The paper describes the most important aspects of a genetic algorithm as a stochastic method for solving various classes of optimization problems. It also describes the basic genetic operator selection, crossover and mutation, serving for a new generation of individuals to achieve an optimal or a ...
2.2. Basic Concepts and Principles of Genetic Algorithms Based on the characteristics of cold chain logistics discussed above, it is inevitable to optimize the distribution path of cold chain logistics, and the genetic algorithm is one of the most effective methods when optimizing the model. Genetic...

This algorithm represents the problem with the concepts of genes, chromosomes/individuals, and population. Candidate solutions are generated and subjected to crossover and mutation. Then, these solutions are evaluated with the fitness function to reach the best solution73. The basic concepts of the ...
As the scheduling problems are formulated, one of the key steps is to identify the meta-algorithm of scheduling heuristics. This step provides the basic concepts of the scheduling heuristics and explains how scheduling decisions will be made. It is expected that the meta-algorithm is general enoug...
A basic pipeline structure is shown in the image below. So the highlighted grey section in the image above is automated using TPOT. This automation is achieved usinggenetic algorithm. So, without going deep into this, let’s directly try to implement it. ...
Whenever the actual number of changed pages on a day is smaller than k, no evaluated algorithm can reach a maximum ChangeRate. This particular detail may cause variations in the ChangeRate obtained by a function when comparing results in distinct days. This variation however does not affect our...
The genetic algorithm is fairly simple. For each generation, it performs two basic operations: Randomly selects N pairs of parents from the current population and produces N new chromosomes by performing a crossover operation on the pair of parents. ...
5.3.5.2Nondominated sorting genetic algorithm II With the understanding of the basic elements in the GA-based approaches for MOO problems, we now discuss NSGA II. In NSGA II, before selection is performed, the population is ranked on the basis of nondomination: all nondominated individuals are...
