Description

Two multi-objective genetic algorithm containing user inputs for:

  • Genetic Algorithm parameters (Population size, Archive size, crossover and mutation probabilities, Max number of generations)
  • A choice between 9 test functions (FON, SCH, POL, KUR, ZDT1, ZDT2, ZDT3, ZDT4, ZDT6)

The pareto front is plotted on a graph at each iteration, and the number of members in the front is printed.

Results are discussed in the report.

File organisation

The two algorithms are contained in separate folders, each containing the steps of the algorithm (initialisation, evaluation, selection, ...).

The program is launched by executing the main.m file.

A folder called "Problemes" contains the functions to test the algorithm.
