This repository presents the implementation of a genetic algorithm for optimizing a metamaterial with a Christmas tree structure, the physics of which is based on the phenomenon of an acoustic black hole.
Program structure:
- optimization_res.m This is the file that is responsible for running the entire program.
- Create_initial_gen.m In this file, the first generation is created, which will be changed in the future
- Cost_func.m This file implements a cost function by which we will determine the course of evolution (the most favorable case has a low cost). In our case, the average value of the pressure coefficient at the point behind the structure
- Ruletka.m This file implements the algorithm for choosing parents - "roulette wheel"
- Crossover.m This file implements the receipt of new chromosomes through crossover (random crossing of parental genes)
- Mutation.m This file implements the process of random mutations of chromosomes
- P_calc.m This file maps the cost function to the corresponding probability. The total probability does not exceed one
- Get_res_table.m This file reads a table of pressure coefficient values at a certain point
- Export_3D.m This file implements the receipt of a 3D structure in the form of a .mph file for its further printing
- Auxiliary functions are also present (corresponding folder)
The details of each part of the program are described in files before the code.
