Overview

PhD/Postdoc in Multiagent Systems and Voting Theory

Game Theory

Location: AI Center FEE CTU, Praha

Full-time

​​Are you passionate about the intersection of game theory, algorithms, and societal challenges? Join our new project New Models of Trust and Voting Robustness in Large Multiagent Systems, and explore the frontier of voting theory and network trust, where democracy meets technology and collaborative systems.

About the Project

In a time when democratic integrity and network security are increasingly at risk, our research seeks to provide computational solutions for understanding and enhancing robustness in elections and trust-based systems. The project combines concepts from coalitional game theory, continuous optimization, and computational social choice to address critical problems, including:

  • Voting systems: Investigate the Margin of Victory, winner robustness, and resilience against attacks in electoral processes.
  • Network trust: Model and analyze reputation systems in peer-to-peer networks using cooperative game theory.
  • Continuous game models: Develop continuous representations of voting and trust systems to overcome computational challenges in traditional discrete methods.

The project is jointly supervised by Tomáš Kroupa from the AI Center at the Czech Technical University in Prague and Martin Koutecký from the Computer Science Institute at Charles University.

Key Research Objectives

  • Develop a continuous computational theory of voting, attacks, and winner robustness.
  • Solve optimization problems related to election safety, manipulation, and coalition formation.
  • Build trust models leveraging cooperative game theory, with applications in networked systems such as e-commerce and social networks.
  • Analyze the computational tractability of fundamental solution concepts in trust games and identify scalable approaches for practical implementation.
