동적 지형분석에서의 전망이론 기반 NPC 의사결정 모델

Abstract

ABSTRACT In this paper, we propose a NPC decision making model based on Prospect Theory which tries to model real-life choice, rather than optimal decision. For this purpose, we analyse the problems of reference point setting, diminishing sensitivity and loss aversion which are known as limitations of the utility theory and then apply these characteristics into the decision making in game. Dynamic Terrain Analysis is utilized to evaluate the proposed model and experimental result shows the method have effects on inducing diverse personality and emergent behavior on NPC.Keywords : Game Artificial Intelligence(게임인공지능), Decision Making Model(의사결정 모델), Prospect Theory(전망이론) Received: Jul. 02, 2014 Accepted: Jul. 21, 2014 Corresponding Author: Dong Hoon Lee(Dongseo University)E-mail: dhl@dongseo.ac.krISSN: 1598-4540 / eISSN: 2287-8211Ⓒ The Korea Game Society.
