Stability in Distance Preservation Games on Graphs

Argyrios Deligkas, Eduard Eiben, Tiger-Lily Goldsmith +2

We introduce a new class of network allocation games called graphical distance preservation games. Here, we are given a graph, called a topology, and a set of agents that need to b…

Dividing Indivisible Items for the Benefit of All: It is Hard to Be Fair Without Social Awareness

Argyris Deligkas, Eduard Eiben, Tiger-Lily Goldsmith +2

In standard fair division models, we assume that all agents are selfish. However, in many scenarios, division of resources has a direct impact on the whole group or even society. T…

Density of Traceable Graphs

Michal Dvořák, Dušan Knop, Michal Opler +3

We establish tight lower and upper bounds on the number of edges in traceable graphs in several classes of dense graphs. A graph is traceable if it has a Hamiltonian path. We show…

When Agents Break Down in Multiagent Path Finding

Foivos Fioravantes, Dušan Knop, Nikolaos Melissinos +1

In Multiagent Path Finding (MAPF), the goal is to compute efficient, collision-free paths for multiple agents navigating a network from their sources to targets, minimizing the sch…

Balanced and Fair Partitioning of Friends

Argyrios Deligkas, Eduard Eiben, Stavros D. Ioannidis +2

In the recently introduced model of fair partitioning of friends, there is a set of agents located on the vertices of an underlying graph that indicates the friendships between the…

Practical approach to -Euclidean Preferences

Michal Dvořák, Dušan Knop, Jan Pokorný +1

An election is a pair of candidates and voters. Each vote is a ranking (permutation) of the candidates. An election is -Euclidean if there is an embedding of both candid…
