Artificial Intelligence for Games

Artificial Intelligence for Games is a specialized discipline within computer science and game development focused on creating believable, responsive, and challenging behaviors for non-player characters (NPCs) and dynamic game systems. Rather than pursuing true consciousness, game AI employs a variety of algorithms and techniques—such as pathfinding, finite state machines, behavior trees, and machine learning—to simulate intelligent decision-making in a computationally efficient manner. The ultimate goal is to enhance the player's experience by crafting immersive worlds, formidable opponents, and helpful allies that react convincingly to the player's actions and the changing game environment.
