,Die Lösung des Beschäftigungsproblems,We show that every .-planar clustered graph admits a straight-line .-planar drawing in which each cluster is represented by an axis-parallel rectangle, thus solving a problem posed by Eades, Feng, Lin, and Nagamochi [.].

Straight-Line Rectangular Drawings of Clustered Graphs,We show that every .-planar clustered graph admits a straight-line .-planar drawing in which each cluster is represented by an axis-parallel rectangle, thus solving a problem posed by Eades, Feng, Lin, and Nagamochi [.].

Skip-Splay: Toward Achieving the Unified Bound in the BST Model,We present skip-splay, the first binary search tree algorithm known to have a running time that nearly achieves the unified bound. Skip-splay trees require only .(. lg lg . + .(.)) time to execute a query sequence . = .. ... ... The skip-splay algorithm is simple and similar to the splay algorithm.

Plane Graphs with Parity Constraints,beled either even or odd. A graph . on . satisfies the parity constraint of a point . ∈ ., if the parity of the degree of . in . matches its label. In this paper we study how well various classes of planar graphs can satisfy arbitrary parity constraints. Specifically, we show that we can always find

Online Priority Steiner Tree Problems,s users. For instance, in QoS multicasting, a source needs to efficiently transmit a message to a set of receivers, each requiring support at a different QoS level (e.g., bandwidth). This can be formulated as the . problem: Here, each link of the underlying network is associated with a priority valu
