Abstract: Autonomous agents interact with the world by processing percepts and taking actions in order to achieve a goal. We consider agents which account for uncertainty when evaluating the state of the world, determine a high level goal based on this analysis, and then select an appropriate plan to achieve that goal. Such knowledge-based agents must take into account facts which are always true (e.g., laws of nature or rules) and facts which have some amount of uncertainty. This leads to probabilistic logic agents which maintain a knowledge base of facts each with an associated probability. We have previously described NILS, a nonlinear systems approach to solving atom probabilities, and compare it here to a hand-coded probability algorithm and a Monte Carlo method based on sampling possible worlds. We provide experimental data comparing the performance of these approaches in terms of successful outcomes in playing Wumpus World. The major contribution is the demonstration that the NILS metho d performs better than the human coded algorithm and is comparable to the Monte Carlo method. This advances the state-of-the-art in that NILS has been shown to have super-quadratic convergence rates. (More)
