Artificial intelligence in video games

In <a href="/facts/Video_game/vmTdNASJ">video games</a>, <a href="/facts/Artificial_intelligence/lJGauQwX">artificial intelligence</a> (AI) is used to generate responsive, adaptive or <a href="/facts/Intelligence/gwEhdLnp">intelligent</a> behaviors primarily in <a href="/facts/Non-player_character/hg6vxMp5">non-playable characters</a> (NPCs) similar to <a href="/facts/Human_intelligence/vgHXwLNL">human-like intelligence</a>. Artificial intelligence has been an integral part of video games since their inception in 1948, first seen in the game Nim. AI in video games is a distinct subfield and differs from academic AI. It serves to improve the game-player experience rather than <a href="/facts/Machine_learning/e0w0XJTu">machine learning</a> or decision making. During the <a href="/facts/Golden_age_of_arcade_video_games/NszLJ8au">golden age of arcade video games</a> the idea of AI opponents was largely popularized in the form of graduated difficulty levels, distinct movement patterns, and in-game events dependent on the player's input. Modern games often implement existing techniques such as <a href="/facts/Pathfinding/x9Ho1cvp">pathfinding</a> and <a href="/facts/Decision_tree_learning/LbPMAwdI">decision trees</a> to guide the actions of NPCs. AI is often used in mechanisms which are not immediately visible to the user, such as <a href="/facts/Data_mining/AH53q5ac">data mining</a> and <a href="/facts/Procedural_generation/I94vq0AQ">procedural-content generation</a>.
In general, game AI does not, as might be thought and sometimes is depicted to be the case, mean a realization of an artificial person corresponding to an NPC in the manner of the <a href="/facts/Turing_test/wEvf9DIr">Turing test</a> or an <a href="/facts/Artificial_general_intelligence/vbxwaq8t">artificial general intelligence</a>.
