Using Meta-Reasoning to Improve the Performance of Case-Based Planning

Case-based planning (CBP) systems are based on the idea of reusing past successful plans for solving new problems. Previous research has shown the ability of meta-reasoning approaches to improve the performance of CBP systems. In this paper we present a new meta-reasoning approach for autonomously improving the performance of CBP systems that operate in real-time domains.

Our approach uses failure patterns to detect anomalous behaviors, and it can learn from experience which of the failures detected are important enough to be fixed. Finally, our meta-reasoning approach can exploit both successful and failed executions for meta-reasoning.

We illustrate its benefits with experimental results from a system implementing our approach called Meta-Darmok in a real-time strategy game. The evaluation of Meta-Darmok shows that the system successfully adapts itself and its performance improves through appropriate revision of the case base.

    Traditionally, strategy games have been played either with miniatures, using physical models of detailed terrain and miniature representations of people and equipment to depict the game state; or on a board, which commonly uses cardboard counters on a hex map.
    Often the computer is expected to emulate a strategically thinking “side” similar to that of a human player (such as directing armies and constructing buildings), or emulate the “instinctive” actions of individual units.
    Popular wargames include Warhammer_40,000 or its fantasy counterpart Warhammer Fantasy. Popular strategic board wargames include risk, Axis and Allies, Diplomacy, and Paths of Glory.
