Computing Stable Matchings under Complementarities and Preference Misalignment
Tatsuya Iwase, Baharak Rastegari, Bahar Rastegari +2
We study many-to-one, two-sided stable matching problems in which preferences are complementary and firms and workers may rank the same allocation differently. Here a coalition is…
Is Limited Information Enough? An Approximate Multi-agent Coverage Control in Non-Convex Discrete Environments
Tatsuya Iwase, Aurélie Beynier, Nicolas Bredeche +2
Conventional distributed approaches to coverage control may suffer from lack of convergence and poor performance, due to the fact that agents have limited information, especially i…
A Polynomial-time Decentralised Algorithm for Coordinated Management of Multiple Intersections
Tatsuya Iwase, Sebastian Stein, Enrico H. Gerding +1
Autonomous intersection management has the potential to reduce road traffic congestion and energy consumption. To realize this potential, efficient algorithms are needed. However,…
A Polynomial-time, Truthful, Individually Rational and Budget Balanced Ridesharing Mechanism
Tatsuya Iwase, Sebastian Stein, Enrico H. Gerding
Ridesharing has great potential to improve transportation efficiency while reducing congestion and pollution. To realize this potential, mechanisms are needed that allocate vehicle…
Self-Fulfilling Signal of an Endogenous State in Network Congestion Games
Tatsuya Iwase, Yukihiro Tadokoro, Daisuke Fukuda
We consider the problem of coordination via signaling in network congestion games to improve social welfare deteriorated by incomplete information about traffic flow. Traditional s…
Linear Game Theory : Reduction of complexity by decomposing large games into partial games
Tatsuya Iwase, Takahiro Shiga
With increasing game size, a problem of computational complexity arises. This is especially true in real world problems such as in social systems, where there is a significant popu…
Pure Nash Equilibrium and Coordination of Players in Ride Sharing Games
Tatsuya Iwase, Takahiro Shiga
In this study, we formulate positive and negative externalities caused by changes in the supply of shared vehicles as ride sharing games. The study aims to understand the price of…
Coordination of Players in Ride-Sharing Games by Signaling
Tatsuya Iwase, Takahiro Shiga
Sharing unused vehicles is one practical solution for traffic congestion. We propose an advanced vehicle-sharing service that maximizes the sharing of vehicles and improves traffic…
