• Approximate Speedup by Independent Identical Processing 

      Hu, X.; Shonkwiler, R.; Spruill, M. C. (Georgia Institute of Technology, 1994-05)
      In this paper we prove that for algorithms which proceed to the next state based on information available from the current state, identical independent parallel processing using stochastic multistart methods always yields ...
    • Random Restarts in Global Optimization 

      Hu, X.; Shonkwiler, R.; Spruill, M. C. (Georgia Institute of Technology, 2009-12-07)
      In this article we study stochastic multistart methods for global optimization, which combine local search with random initialization, and their parallel implementations. It is shown that in a minimax sense the optimal ...
