    Maximum lifetime data sensing and extraction in energy constrained networked sensor systems
    Download  halcyon.usc.edu
    We focus on data gathering problems in energy constrained networked sensor systems. The system operates in rounds where a subset of the sensors generate a certain number of data p...

    A Lower Bound for the Shortest Path Problem
    Download  people.cs.uchicago.edu
    We show that the Shortest Path Problem cannot be solved in o(log n) time on an unbounded fan-in PRAM without bit operations using poly(n) processors even when the bit-lengths of t...

    Combining Exact and Heuristic Approaches for the Capacitated Fixed-Charge Network Flow Problem
    Download  www2.isye.gatech.edu
    We develop a solution approach for the fixed charge network flow problem (FCNF) that produces provably high-quality solutions quickly. The solution approach combines mathematica...
