Artificial Intelligence, also known as AI, is defined as thescienceof making computers exhibit human behaviour.
Artificial Intelligence isimplemented in many fields, including: expert systems, game AI,robotics, natural language,andneural networks 3.Another fieldof AI is machine learning, inwhich computers maycreate their own solutions to problems 2. All these specializations focuson one thing: enabling computers to interact with human users and to behavelike humans rather than machines.
Many of these fields have included newforms of softwaretechnology used worldwide today such as chess games on your computerandvoice recognition on mobile phones. No computer today can displaycompleteartificial intelligence, where the computercanbehave exactlylike a human being. However, progress in the field has been made, the most ofitbeing in the specialization of gameAI 3.
1.2 What is gameAI? Game AI encompasses many features of game development which help enhance the experience oftheplayer. Beal defines game AI as “programming computers to playgames against human opponents” 3.
While thisis true, it is a partial definitionof game AI. The book Game AI Pro 2 offers a more precise and knowledgeable definition for the term: asa general overview, game AI is the process of applied decision-making in video games. This can be thought of as the computer deciding how toreact based on the input received from the player; the computer has a freesetof choices and can decide foritself instead of a machine-like process. However, it is important to recognize that games can be created withouttheuse of game AI techniques.
Games like Tetris are very systematic,where the user chooses where to place a block and the computergenerates another block. There is neither emotion being conveyed in the game nor asense ofinteraction. This is what game AI helps achieve2.Rabin elaborates on this idea perfectlyby saying, “it is the sensation thatsomething on the otherside ofthe screen is almost alivethat makes gameAIunique and powerful.
This feeling arises from observing the game’making decisions’ about what happens next” 2:4-5.
