AI Search Algorithms for Problem Solving

How do artificial intelligence systems find the optimal path, solve complex puzzles, or make strategic decisions? At the core of classic AI lies search theory—the structured process of navigating through possibilities to find a solution. This text-based course guides you through the essential concepts and algorithms that power intelligent problem-solving agents. By reading through clear explanations and working through conceptual exercises, you will develop a deep understanding of how to model real-world challenges as search spaces. You will transition from basic exploration strategies to advanced, informed search techniques used in modern AI planning and decision-making systems. What you'll learn: - Understand the core terminology of state-space representation, nodes, transitions, and goal states. - Implement uninformed search strategies including depth-first, breadth-first, and uniform cost search. - Apply heuristic search methods such as Greedy Best-First and A* search to find optimal solutions efficiently. - Explore advanced search paradigms including local search, hill climbing, and simulated annealing. - Practice designing effective heuristic functions to optimize search performance in complex domains. - Analyze the time and space complexity of different search algorithms to choose the right tool for any problem. The course begins with fundamental definitions and the conceptual formulation of search problems. You will then progress step-by-step through classic algorithms, heuristic design, and modern optimization techniques, testing your knowledge with written practice scenarios. This course is designed for aspiring developers, computer science students, and AI enthusiasts who want to build a strong theoretical and practical foundation in algorithmic problem-solving. No prior background in artificial intelligence is required. Start reading today to unlock the algorithmic strategies that drive intelligent automation.
