Evolutionary Algorithm

How Evolutionary Algorithm Works

The Evolutionary Algorithm works by initializing a population of potential solutions and then evolving them through several generations. Each generation involves selecting the best solutions, allowing them to reproduce, and creating new solutions through genetic operations like mutation and crossover. This iterative process continues until a satisfactory solution is found or a predetermined number of generations is reached.

Types of Evolutionary Algorithm

• Genetic Algorithms. Genetic algorithms use concepts from natural selection to optimize solutions. They encode potential solutions as chromosomes and iteratively evolve the population using selection, crossover, and mutation operators.
• Genetic Programming. This algorithm evolves computer programs to solve problems. Instead of manipulating fixed-length strings, it evolves tree structures representing program code, allowing the creation of complex algorithms.
• Evolution Strategies. Focused primarily on optimization problems, evolution strategies apply mutation to a set of parameters while selecting the best performing candidates based on their fitness in reaching the desired outcome.
• Differential Evolution. This variant optimizes problems by using differences between randomly selected individuals to create new candidate solutions, promoting diversity among potential solutions while driving towards optimal results.
• Estimation of Distribution Algorithms. These algorithms use probabilistic models to describe the distribution of promising solutions, allowing for the sampling of new solutions based on this probabilistic model and enhancing the exploration of the solution space.

Algorithms Used in Evolutionary Algorithm

• Genetic Operators. Genetic operators include selection, crossover, and mutation which are essential for generating new solutions in the population and driving the evolution process.
• Fitness Function. This algorithm evaluates how good a solution is concerning the problem at hand, effectively ranking each candidate solution based on its performance.
• Selection Techniques. Selection techniques are methods like tournament selection or roulette wheel selection that determine which individuals from a population will contribute to the next generation.
• Recombination and Crossover. Recombination is a technique that combines parts of two or more parents’ solutions to create offspring, allowing the expression of useful traits from multiple sources.
• Mutation Processes. Mutation introduces random changes to a solution, promoting genetic diversity and allowing the algorithm to explore new areas of the solution space, thus preventing premature convergence.
