Improved Complexity for Power Edge Set Problem. We show that . remains .-hard in planar graphs with degree at most five. This result is extended to bipartite planar graphs with degree at most six. We also show that . is hard to approximate within a factor lower than . in the bipartite case (resp. .), unless ., (resp. under .). We also show that

On the Maximum Crossing Numberum number of crossings of a geometric graph and that the weighted geometric case is NP-hard to approximate. We strengthen these results by showing hardness of approximation even for the unweighted geometric case and prove that the unweighted topological case is NP-hard.

Approximation Results for the Incremental Knapsack Problemural assumption that each item can be packed in the first time period. For this variant, we discuss different approximation algorithms suited for any number of time periods and provide an algorithm with a constant approximation factor of . for the case with two periods.
