The Evolutionary Advantage

Just as species adapt and evolve in response to their environment, evolutionary algorithms seek to find optimal solutions by iteratively improving candidate solutions. These algorithms resemble the natural selection process, where individuals with higher fitness (ability to solve the problem) are more likely to survive and contribute offspring.

From Biology to Algorithms

Evolutionary algorithms are a type of metaheuristic, meaning they optimize problems without relying on specific domain knowledge. They start with a population of individuals, each representing a potential solution. These individuals are then evaluated based on a fitness function that measures how well they solve the problem.

Individuals with higher fitness are more likely to be selected for reproduction, while lower-fitness individuals are gradually phased out. During reproduction, crossover and mutation operators are applied to genetic material (similar to DNA) to create new individuals.

Genetic Operations

• Crossover combines the genetic material of two individuals to create a new one, fostering genetic diversity.
• Mutation randomly alters genetic material, introducing variation that may lead to novel solutions.
