The computational difficulty of manipulating an election
We show how computational complexity might protect the integrity of social choice. We exhibit a voting rule that efficiently computes winners but is computationally resistant to strategicExpand

Voting schemes for which it can be difficult to tell who won the election
We show that a voting scheme suggested by Lewis Carroll can be impractical in that it can be computationally prohibitive (specifically, NP-hard) to determine whether any particular candidate has wonExpand

Auction-Based Multi-Robot Routing
TLDR
We propose a generic framework for auction-based multi-robot routing and analyze a variety of bidding rules for different team objectives. Expand

Individual differences versus social dynamics in the formation of animal dominance hierarchies
Linear hierarchies, the classical pecking-order structures, are formed readily in both nature and the laboratory in a great range of species including humans. However, the probability of gettingExpand

The Power of Sequential Single-Item Auctions for Agent Coordination
TLDR
We analyzed a coordination system based on sequential single-item auctions, demonstrating that it combines the advantages of both. Expand

Lazy Theta*: Any-Angle Path Planning and Path Length Analysis in 3D
TLDR
The shortest paths formed by the edges of 8-neighbor 2D grids can be up to ≈ 8% longer than the shortest paths in the continuous environment, which highlights the need for smart path planning algorithms in 3D. Expand

New Results on the Old k-opt Algorithm for the Traveling Salesman Problem
TLDR
Local search with k-change neighborhoods is perhaps the oldest and most widely used heuristic method for the traveling salesman problem, yet almost no theoretical performance guarantees for it were previously known. Expand

On Honey Bees and Dynamic Server Allocation in Internet Hosting Centers
TLDR
We propose a new decentralized honey bee-mimicking server allocation algorithm which dynamically allocates servers to satisfy request loads. Expand

The Generation of Bidding Rules for Auction-Based Robot Coordination
TLDR
In this paper, we propose the first such method and demonstrate it by deriving bidding rules for three possible team objectives of a multi-robot exploration task. Expand
