Technical report TR07-06. The effectiveness of heuristics search is influnced by the accuracy of the heuristic values. State space abstractions have been proved to be effective for generating admissible heuristics. In this paper, A general definition for abstractions is given. As a demonstration...
For zero-sum games, we have efficient solution techniques. Unfortunately, there are interesting games that are too large to solve. Here, a popular approach is to solve an abstract game that models the original game. We assume that more accurate the abstract games result in stronger strategies....
In this thesis, we study theoretically and empirically the additive abstraction-based heuristics. First we present formal general definitions for abstractions that extend to general additive abstractions. We show that the general definition makes proofs of admissibility, consistency, and...
An agent in an adversarial, imperfect information environment must sometimes decide whether or not to take an action and, if they take the action, must choose a parameter value associated with that action. Examples include choosing to buy or sell some amount of resources or choosing whether or...
Technical report TR08-05. The following report describes some techniques that generalize and attempt to improve upon the Coarse-to-Fine Dynamic Programming (CFDP) algorithm developed by Christopher Raphael. CFDP uses a hierarchy of abstraction graphs, iteratively searches to find optimal...
Technical report TR09-04. Abstraction is a popular technique for speeding up planning and search. A problem that often arises in using abstraction is the generation of abstract states, called spurious states, from which the goal state is reachable in the abstract space but for which there is no...
This thesis consists of two parts. First, we invented an abstraction framework called multimapping which allows multiple admissible heuristic values to be extracted from one abstract space. The key idea of this technique is to design a multimapping function which maps one state in the original...
My paintings have a narrative element in the sense that I use symbolism, references to popular culture, and figures that are staged within expressionistic allegorical spaces. These spaces are visualized as a stage or film set in order to evoke a sense of cinematic storytelling, and the...
Real-time strategy (RTS) games are war simulation video games in which the players perform several simultaneous tasks like gathering and spending resources, building a base, and controlling units in combat against an enemy force. RTS games have recently drawn the interest of the game AI research...
Game theoretic solution concepts, such as Nash equilibrium strategies that are optimal against worst case opponents, provide guidance in finding desirable autonomous agent behaviour. In particular, we wish to approximate solutions to complex, dynamic tasks, such as negotiation or bidding in...
