Genetic Algorithms (GAs)

A search heuristic that mimics the process of natural evolution to find optimal solutions.

John Holland

Considered the father of Algorithmic Evolution, he developed Genetic Algorithms.

Fitness Function

A function that evaluates how well a solution solves the given problem.

Global Search Heuristics

Techniques that do not search for specific hypotheses but explore potential solutions broadly.

Elitism

A strategy in Genetic Algorithms that ensures the best solutions carry over to the next generation.

Crossover

A genetic operator that combines two parent solutions to produce offspring solutions.

Mutation

A genetic operator that introduces small changes to a solution to maintain genetic diversity.

MAXONE Problem

An example problem where the objective is to maximize the number of ones in a binary string.

Generational Method

An iterative process of evolving solutions in Genetic Algorithms by producing new generations.

Two-Point Crossover

A crossover method that selects two points to swap segments between two parent solutions.

Single-Point Crossover

A crossover method that selects one point to swap segments between two parent solutions.

Probabilistic Approach

A method used in Genetic Algorithms to decide whether to keep or discard a solution based on its fitness.

Genetic Programming

An extension of Genetic Algorithms where the evolving individuals are full computer programs instead of binary strings.

Program Tree

A representation in Genetic Programming where a computer program is structured in a tree format.

Primitive Functions

Basic functions used in Genetic Programming to define the operations that can be performed on data.
