,Spätergebnisse operierter Mitralstenosen,ecretary problem towards the knapsack secretary problem. Our algorithm is simple: It . the value of size-1 items by a factor . and then uses the size-oblivious approach by Albers, Khan, and Ladewig. We show by a nontrivial analysis that this algorithm achieves a competitive ratio of 1/. if and only

On the positive side we show that the maximum geometric independent set in a set of axis-aligned unit-height rectangles can be 4-approximated using only . bits.

,Locating Service and Charging Stations,o locate the facilities such that each client can follow its path without any detours. For both problems, our objective is to minimize the number of charging stations..For all three problems, when the underlying graph is a tree and the facility can be located at any vertex on the tree, we show that

,Scheduling with Machine Conflicts, to solve the problem for the case of unit jobs . on special graph classes. As our main result, we solve . for bipartite graphs by using structural insights for conflict graphs of star forests. As the set of active machines at each point in time induces a bipartite graph, the insights yield a local
