Applications of Search Theory to Coordinated Searching by Unmanned Aerial Vehicles
<p>Concepts in optimal search theory have been used in human-based aerial search since World War II. This thesis addresses the technical and theoretical issues necessary to apply this crucial theory to search path planning for Small Unmanned Aerial Vehicles (SUAVs). A typical search often requires …

Toward Real-Time Planning for Robotic Search
This work addresses applications of search theory where a mobile search agent seeks to find an unknown number of stationary targets randomly distributed in a bounded search domain. We assume that the search mission is subject to a time or distance constraint, and that the local environmental …

Smart Search Engine For Information Retrieval
This project addresses the main research problem in information retrieval and semantic search. It proposes the smart search theory as new theory based on hypothesis that semantic meanings of a document can be described by a set of keywords. With two experiments designed and carried out in this …

Dealers, insiders and bandits : learning and its effects on market outcomes
… and learning have both been the focus of much research in computer science, economics and finance theory. However, we are at a critical stage in defining the direction of future research in these areas. It is now clear that realistic learning problems faced by agents in market environments are …

Rent adjustment mechanism for the multifamily housing market
… employed incorporates the principal argument of search theory that vacancy ultimately determines rent levels. Various time lags on the vacancy rate are tested for each metropolitan area in order to better understand the timing of the effect of the vacancy rate on market rents and to find the best …

Modeling Human Movement in the Wilderness: Navigating Lost Person Behavior and Searcher Response
Search and rescue (SAR) outcomes hinge on two behavioral uncertainties: how lost people move through complex landscapes and how ground teams search those landscapes. This dissertation develops a unified, data-driven view of both. First, we present a dynamic, agent-based model of lost person …

An endogenous search model and its applications
The existing literature on empirical job search models concentrates on studying the effects of unemployment insurance (UI) benefits, and the primary interest has been in male displaced workers. It is usually assumed that displaced workers start to search for new jobs immediately after the …

Multimarket Search
The extensive literature on searching for price information deals almost exclusively with the search for the price of a single good. Since consumers would like to maximize the utility of consumption, a more general problem than minimizing the price of one good, search theory should consider the …

A Model of Non-Routine Organizational Search: Broadcast Search as an Alternative Knowledge-Sourcing Mechanism in the Pharmaceutical Industry
Combining Cyert and March's (1963) model of search with foundational concepts from evolutionary theory (Nelson & Winter, 1982), this dissertation scrutinizes the expansion of search and develops a refined framework for organizational search behavior. Special emphasis is put on the aspect of search …

Cow-path games : tactical strategies to search for scarce resources
This thesis investigates search scenarios in which multiple mobile, self-interested agents, cows in our case, compete to capture targets. The problems considered in this thesis address search strategies that reflect (i) the need to efficiently search for targets given a prior on their location, and …
