Online and Incremental Fractional Vertex Cover on Trees
Júlia Baligács, Bartłomiej Bosek, Yann Disser +5
In this paper we study the fractional vertex cover problem on trees in two related models: online and incremental. In the online model, the vertices of the tree are known a priori…
Incremental Submodular Maximization: Better Than Greedy
Marcin Bienkowski, Joakim Blikstad, Jarosław Byrka +3
We consider submodular maximization under increasing cardinality constraint and ask for a good incremental solution, i.e., an ordering of the ground set such that each prefix of th…
Incremental-Decremental Maximization
Yann Disser, Max Klimm, Annette Lutz +1
We introduce a framework for incremental-decremental maximization that captures the gradual transformation or renewal of infrastructures. In our model, an initial solution is trans…
Bicriterial Approximation for the Incremental Prize-Collecting Steiner-Tree Problem
Yann Disser, Svenja M. Griesbach, Max Klimm +1
We consider an incremental variant of the rooted prize-collecting Steiner-tree problem with a growing budget constraint. While no incremental solution exists that simultaneously ap…
A -Approximation for Tricolored Non-crossing Euclidean TSP
Júlia Baligács, Yann Disser, Andreas Emil Feldmann +1
In the Tricolored Euclidean Traveling Salesperson problem, we are given~ sets of points in the plane and are looking for disjoint tours, each covering one of the sets. Arora (…
Exploration of graphs with excluded minors
Julia Baligacs, Yann Disser, Irene Heinrich +1
We study the online graph exploration problem proposed by Kalyanasundaram and Pruhs (1994) and prove a constant competitive ratio on minor-free graphs. This result encompasses and…
