Genetic algorithm (genetic algorithm, GA) is a new global optimization algorithm developed in recent years, it borrows the viewpoint of biological genetics, through the mechanism of natural selection, heredity, mutation and so on, realizes each individual's adaptability enhancement. This reflects the nature of the "natural selection, survival of the fittest" evolutionary process.
Professor Holland the idea of GA
Genetic Algorithm (GA), as a classical evolutionary algorithm, has formed a more active research field in the world since Holland was put forward. A lot of researches on GA are presented, and various improved algorithms are proposed to improve the convergence speed and accuracy of the algorithm. Genetic algorithm adopts selection, crossover, mutation operation, Search for the optimal solution in the pr

The new GA version provides CSV, TSV, TSV for Excel, and Excel data export methods.
Go to any report page, click Export, and select export option to export the desired data and save it as an Excel report file for local data processing.
The report page displays the amount of data, the exported amount of data, and the last row is the summarized data. The report page of GA can display a maximum of 500 data rec
