Toward a Universal Mapping Algorithm for Accessing Trees in Parallel Memory Systems
We study the problem of mapping the N nodes of a complete t-ary tree on M memory modules so that they can be accessed in parallel by templates, i.e. distinct sets of nodes. Typica...

Progressive Route Calculation Protocol for Wireless Mesh Networks
—Although network-wide flooding in reactive routing protocols like AODV [1] facilitates the discovery of optimal routes, they engender large control overhead. Some efficient floo...

Combining a Memetic Algorithm with Integer Programming to Solve the Prize-Collecting Steiner Tree Problem
The prize-collecting Steiner tree problem on a graph with edge costs and vertex profits asks for a subtree minimizing the sum of the total cost of all edges in the subtree plus th...

Pebbling and optimal pebbling in graphs
Given a distribution of pebbles on the vertices of a graph G, a pebbling move takes two pebbles from one vertex and puts one on a neighboring vertex. The pebbling number (G) is th...
