Abstract
Search of an unknown space by a physical agent (such as an autonomous vehicle) is unique in search as the customarily most important goal (to reduce the computation time required to obtain the shortest distance) is not as important as minimal movement. there is a real-time aspect since the agent is actually moving; using energy every step of the way. Having limited energy resources and knowledge of the terrain (only adjacent nodes), the key factor for the physical agent's search algorithm is reduction of steps. Hence, any heuristic that can help keep step count to a minimum must be considered. Korf and Shing addressed this in separate works. Both made use of known information about the frontier node's distance from the current node in addition to a heuristic estimating the distance from goal. In this thesis, we present a simple genetics-based method to produce adaptive, efficient multi-heuristic search strategies for the real-time problem. Extensive empirical study shows that this approach produced search strategies with much better performance over existing search algorithms for most terrain types. The methodologies used to develop these improved strategies for our specific case, are also applicable to a multitude of real-time search/optimization problems in the general case.

    A game theory analysis of proposed strategies of an aerial search for a mobile surface target. 

    Smith, Charles James (Monterey, California. U.S. Naval Postgraduate School, 1966-10);
    This thesis investigates the problem of aerial search for a mobile surface target. The initial position of the target is known, and a certain amount of time elapses before the search begins. The target has a variety of ...
