Bounty hunting has been shown to solve the multiagent task allocation problem robustly in noisy and dynamic scenarios with multiple other agents of unknown quality. This bounty hunting model does not require task exclusivity, but does require task commitment. We examine eliminating this second requirement, thus allowing bounty hunters to commit to tasks but abandon them later (to jump ship) for...

Taddy (2013) proposed multinomial inverse regression (MNIR) as a new model of annotated text based on the influence of metadata and response variables on the distribution of words in a document. While effective, MNIR has no way to exploit structure in the corpus to improve its predictions or facilitate exploratory data analysis. On the other hand, traditional probabilistic topic models (like la...

Mit der Entwicklung des Navigations-Centers „TelNav“ durch die ExperTeam AG wird ein innovativer „Location Based Service (LBS)“ geschaffen, der mittels Ortung und Navigation über das Mobiltelefon oder den PDA („Personal Digital Assistent“) jeden Nutzer, der irgendwo in Deutschland unterwegs ist, auf dem optimalen Weg schnell und sicher zu seinem Ziel führt. Dies geschieht unabhängig vom kartogr...

Many multiagent systems require allocation of agents to tasks in order to ensure successful task execution. Most systems that perform this allocation assume that the quantity of agents needed for a task is known beforehand. Coalition formation approaches relax this assumption, allowing multiple agents to be dynamically assigned. Unfortunately, many current approaches to coalition formation lack...

The aim of this work is to develop a new type of service for predicting and communicating urban activity. This service provides short-term predictions (hours to days), which can be used as a basis for different types of resource allocation and planning, e.g. concerning public transport, personnel, or marketing. The core of the service consists of a forecasting engine that based on a prediction ...

We develop an agent-based model of foraging behavior based on ecological parameters of the environment and prey characteristics measured in the Mbaracayu Reserve Paraguay. We then compare predicted foraging behavior from our model to the ethnographically observed behavior of Ache hunter-gatherers who inhabit the region and show a close match for daily harvest rates, time allocation, and species...

We describe a new platform for system dynamics modeling that supports detailed and object oriented modeling while preserving attractive features of existing tools, including a completely declarative language with a graphical representation. New concepts supporting this platform include collections of entities, attributes, relationships, aggregation and allocation functions, and actions, which a...

Competitive bidding is the main mechanism for allocation of construction projects and consequently price determination of the construction services in the A/E/C industry. While different aspects of construction bidding have been studied in the literature, there is still a need for developing a comprehensive model that captures the complex dynamics of bidding environment by considering interacti...

Illegal extraction of forest resources is fought, in many developing countries, by patrols that seek to deter such activity by decreasing its profitability. With a limited budget, a patrol strategy will seek to distribute the patrols throughout the forest, in order to minimize the resulting amount of extraction that occurs or maximize the amount of “pristine” forest area. Prior work in forest e...

In Copenhagen climate conference China government promised that China would cut down carbon intensity 40e45% from 2005 by 2020. CET (carbon emissions trading) is an effective tool to reduce emissions. But because CET is not fully implemented in China up to now, how to design it and its potential impact are unknown to us. This paper studies the potential impact of introduction of CET on China’s ...
