Bicriteria Approximation Tradeoff for the Node-Cost Budget Problemnteed a (2,.(log.)) bicriteria approximation, i.e. the solution’s profit is at least a fraction of . of an optimum solution respecting the budget, while its cost is at most twice the given budget. We improve these results and present a bicriteria tradeoff that, given any . ∈ (0,1], guarantees a .-approximation.

NP-complete and provide pseudo-polynomial time algorithms. For a special case of graphs with treewidth two, we give a polynomial time algorithm.

Die Struktur des Planungssystems= . + 1 is also sufficient for a tree . with ., which leads a linear time algorithm for computing .(.) under this condition. We then show that .(.) can be computed in . time for any tree .. Combining these, we finally obtain an . time algorithm, which substantially improves upon previously known results.
