Conversely, we show how certain notions that have become of importance within parameterized algorithmics can be useful to keep in mind for combinatorialists. We hope that this accoun

Approximation Results for the Incremental Knapsack Problemtain period, it cannot be removed afterwards. The problem calls for maximizing the sum of the profits over the whole time horizon. In this work, we manage to prove the tightness of some approximation ratios of a general purpose algorithm currently available in the literature. We also devise a Polyno

Derandomization for ,-Submodular Maximizationation of a .-submodular function is NP-hard, and approximation algorithms have been studied. Most of algorithms use randomization and achieve the approximation ratio as the expected value. For unconstrained submodular maximization, [Buchbinder and Feldman 2016] gave a derandomization scheme, and sho

Complexity Dichotomies for the Minimum ,-Overlay Problem by every hyperedge of . contains some member of . as a spanning subgraph. While it is easy to see that the complete graph on |.(.)| overlays . on a hypergraph . whenever the problem admits a solution, the . .-. problem asks for such a graph with the minimum number of edges. This problem allows to g
