Ahmed Nabil Belbachir,Peter Michael Göbell. Furthermore, there is no overlap between any two subtrees selected in the solution. We prove that this problem is NP-hard and present a fully polynomial-time approximation scheme (FPTAS) as a solution.

New Min-Max Theorems for Weakly Chordal and Dually Chordal Graphs,n polynomial time whenever . is odd, and NP-hard when . is even. Motivated by our use of hypergraphs, we define a class of hypergraphs which lies strictly in between the well studied classes of acyclic hypergraphs and normal hypergraphs.

Coverage with ,-Transmitters in the Presence of Obstacles, . “walls”, represented as line segments in the plane. We develop lower and upper bounds for the number of .-transmitters that are necessary and sufficient to cover a given collection of line segments, polygonal chains and polygons.

Constrained Surface-Level Gateway Placement for Underwater Acoustic Wireless Sensor Networks,is paper addresses the connected (or survivable) Constrained Surface-level Gateway Placement (C-SGP) problem for 3-D underwater acoustic sensor networks. Given a set of candidate locations where SGs can be placed, our objective is to place minimum number of SGs at a subset of candidate locations suc
