What is a production system?

Production systems in artificial intelligence (AI) consist of rules that guide the creation of programs capable of problem-solving. These systems are structured around production rules, each with a condition and corresponding action. When a condition is met, the action is executed, allowing the system to progress towards a solution.

What is an evolutionary algorithm?

An evolutionary algorithm (EA) is a type of artificial intelligence-based computational method that solves problems by mimicking biological evolution processes such as reproduction, mutation, recombination, and selection. EAs are a subset of evolutionary computation and are considered a generic population-based metaheuristic optimization algorithm.
