Constrained Surface-Level Gateway Placement for Underwater Acoustic Wireless Sensor Networks,h that it is connected (or 2-connected) from any USN to the base station. We propose a polynomial time approximation algorithm for the connected C-SGP problem and survivable C-SGP problem, respectively. Simulations are conducted to verify our algorithms’ efficiency.

A Constant-Factor Approximation Algorithm for the Link Building Problem,e algorithm where we choose backlinks from nodes with high PageRank values compared to the outdegree and show that the naive algorithm performs much worse on certain graphs compared to the constant factor approximation scheme.

Approximation Algorithm for the Minimum Directed Tree Cover, to approximate DTCP with the same ratio as for SCP. We show that this expectation can be satisfied in some way by designing a purely combinatorial approximation algorithm for the DTCP and proving that the approximation ratio of the algorithm is max {2, ln (..)} with .. is the maximum outgoing degree of the nodes in ..

Ahmed Nabil Belbachir,Peter Michael G?belult. For graphs with small or moderate branchwidth, the CDS problem instances with size up to a few thousands edges can be solved in a practical time and memory space. This suggests that the branch-decomposition based algorithms can be practical for the planar CDS problem.

Combined with the result of Bonichon, Gavoille, Hanusse and Ilcinkas, who prove an upper bound of 2 on the stretch factor of Θ., we obtain an upper bound of 17.7 on the stretch factor of ...
