Interference-free Walks in Time: Temporally Disjoint Paths
Nina Klobas, George B. Mertzios, Hendrik Molter +2
We investigate the computational complexity of finding temporally disjoint paths or walks in temporal graphs. There, the edge set changes over discrete time steps and a temporal pa…
Matching in Stochastically Evolving Graphs
Eleni C. Akrida, Argyrios Deligkas, George B. Mertzios +2
This paper studies the maximum cardinality matching problem in stochastically evolving graphs. We formally define the arrival-departure model with stochastic departures. There, a g…
Exact and Approximate Algorithms for Computing a Second Hamiltonian Cycle
Argyrios Deligkas, George B. Mertzios, Paul G. Spirakis +1
In this paper we consider the following total functional problem: Given a cubic Hamiltonian graph and a Hamiltonian cycle of , how can we compute a second Hamiltonian…
Computing Maximum Matchings in Temporal Graphs
George B. Mertzios, Hendrik Molter, Rolf Niedermeier +2
Temporal graphs are graphs whose topology is subject to discrete changes over time. Given a static underlying graph , a temporal graph is represented by assigning a set of integ…
How fast can we reach a target vertex in stochastic temporal graphs?
Eleni C. Akrida, George B. Mertzios, Sotiris Nikoletseas +3
Temporal graphs are used to abstractly model real-life networks that are inherently dynamic in nature. Given a static underlying graph , a temporal graph on is a seque…
Sliding Window Temporal Graph Coloring
George B. Mertzios, Hendrik Molter, Viktor Zamaraev
Graph coloring is one of the most famous computational problems with applications in a wide range of areas such as planning and scheduling, resource allocation, and pattern matchin…
