A DDLM-based Method for Solving Distributed Problems Tang Yi
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
DDLM: Distributed discrete Lagrange Method • An extension to DLM • Main iteration
DDLM based SAT Solver • Transformed problems: • Update the iteration
Experimental Results • 2000 runs in uf100-430 :
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.
