Presentation Transcript

  1. A DDLM-based Method for Solving Distributed Problems Tang Yi

  2. Lagrange Multiplier Method • Lagrange Multiplier min f(x) subject to g(x) = 0 Lagrange Function: L(x, ) = f(x) +  g(x) • Traditional method is continuous • Discrete method : DLM

  3. DDLM: Distributed discrete Lagrange Method • An extension to DLM • Main iteration

  4. DDLM based SAT Solver • Transformed problems: • Update the iteration

  5. Experimental Results • 2000 runs in uf100-430 :

  6. Conclusion • A method to solve distributed CSPs with some mathematics equations. • More mathematics theory can be added to improve performance • Also exists local minimum, need other methods to escape from a local minimum.
