Improvement to the Sequential Combination Tree Algorithm

  • Received Date: 02 Aug 2005
  • Publish Date: 25 Oct 2006
  • To increase the efficiency of sequential combination tree method,it is necessary to make full use of information in the constraint conditions.Based on a thorough analysis of the method,the concepts such as ultimate difference,necessary variables,and ineligible variables were proposed to combine constraints as a whole.A new algorithm was presented,in which the compatibility of constraints are determined and taken as a criterion to cut branches.It was proved that if all the necessary variables taking 1 is a feasible solution,it is the optimum solution.The flow chart of the new algorithm was presented.
