Preliminary study of genetic algorithm

Wrote a 10 number of the maximum sum, the value range of what 0-99, because the state space is relatively large, so the probability of mutation selection of 0.3, larger, crossover probability 0.8, population size 100, genetic algebra 1000effect, not very ideal, distance 990 of the limit there is no small gapAs can be seen, only 8 times above 950, and after the increase of the genetic algebra to 10000, the effect did not increase significantly, quite failed#include using namespacestd;Const Double

The following code simulates the evolution of flowers.The number of flowers is 10, and 50 generations have been made. By running the program, you will find that through continuous evolution, the overall adaptability of the population to the environment is gradually increasing (fitness value is reduced ).

particular, the parameters of each individual neural network in the POC are generated by randomly disturbing the parameters of a single "parent" neural network, and then the neural network of each pseudo descendant is trained and evaluated according to the target. In the humanoid gait task, each pseudo descendant neural network controls the movement of a Mujoco robot, scoring the fitness of each network based on the quality of the robot's Walk (calle

Genetic Algorithm and direct search toolbox study note 10-Working Principle of Genetic Algorithm

How genetic algorithms work 1. algorithm Overview The following outline summarizes the algorithm work process. 1. The algorithm generates an initial and random population. 2. Algorithms generate a series of new populations. In each step of the algorithm, the algorithm uses the individual of the current population to generate the next generation of the population. To generate a new population, the algorithm performs the following steps: A. Calculate the fitne

Particle swarm Algorithm (1) Introduction to----particle swarm algorithm __ algorithm

used to solve the optimization problem. In PSO, the potential solution of each optimization problem can be imagined as a point in the D-dimensional search space, which we call "particle" (particle), and all particles have an adaptive value (Fitness value) determined by the target function. Each particle has a speed that determines the direction and distance of their flight, and the particles follow the current optimal particle to search the solution

Huang baiming's film "ye Q sequence" was released recently, and has received a lot of praise from fans. A press conference was held recently during the download of "ye Wen sequent". Huang baiming announced that he would launch the next year's "ye Wen" sequent "ye Wen 2". Huang baiming again said that when he downloaded "ye wen2" in the sequel to ye wen2 next year, he said that the film will be added to another important role, that is, ye wen's proud disciple Bruce Lee, the selection will be det
