Advanced Search Techniques

While uninformed and informed searches form the foundation of search algorithms, advanced techniques extend their capabilities:

  1. Metaheuristic Algorithms: Techniques like Genetic Algorithms, Simulated Annealing, and Particle Swarm Optimization optimize complex problems by combining heuristic principles with stochastic methods.

  2. Adversarial Search: Applied in competitive environments, such as games, where multiple agents with conflicting goals interact (e.g., the Minimax algorithm).

  3. Constraint Satisfaction Problems (CSPs): Focused on finding solutions that meet specific constraints, often using methods like backtracking and local search.
