Abstract

This paper presents GHOST, a combinatorial optimization framework that a real-time strategy (RTS) AI developer can use to model and solve any problem encoded as a constraint satisfaction/optimization problem (CSP/COP). We show a way to model three different problems as a CSP/COP, using instances from the RTS game StarCraft as test beds. Each problem belongs to a specific level of abstraction (the target selection as reactive control problem, the wall-in as a tactics problem, and the build order planning as a strategy problem). In our experiments, GHOST shows good results computed within some tens of milliseconds. We also show that GHOST outperforms state-of-the-art constraint solvers, matching them on the resources allocation problem, a common combinatorial optimization problem.

ghost:一个用于实时问题的组合优化框架
本文介绍了GHOST,这是一个组合优化框架,实时策略(RTS) AI开发者可以使用它来建模和解决任何编码为约束满足/优化问题(CSP/COP)的问题。我们使用RTS游戏《星际争霸》中的实例作为测试平台,展示了一种将三个不同问题建模为CSP/COP的方法。每个问题都属于特定的抽象层次(目标选择是反应性控制问题,进驻墙是战术问题,构建顺序计划是战略问题)。在我们的实验中,GHOST在几十毫秒内就得到了很好的计算结果。我们还表明GHOST优于最先进的约束求解器,在资源分配问题(一个常见的组合优化问题)上与它们相匹配。

期刊介绍: Cessation. The IEEE Transactions on Computational Intelligence and AI in Games (T-CIAIG) publishes archival journal quality original papers in computational intelligence and related areas in artificial intelligence applied to games, including but not limited to videogames, mathematical games, human–computer interactions in games, and games involving physical objects. Emphasis is placed on the use of these methods to improve performance in and understanding of the dynamics of games, as well as gaining insight into the properties of the methods as applied to games. It also includes using games as a platform for building intelligent embedded agents for the real world. Papers connecting games to all areas of computational intelligence and traditional AI are considered.
