Algorithm 3

Rule selection algorithm with “competition for resource”.

INPUT: rule set A (the output of Algorithm 2)

OUTPUT: rule set without competition for resource

(1) Select one rule form randomly, adding into , and delete from at the same time.

(2) For every rule in except , if there is competition for resource between and ,

  delete from . If is not null, return (1), else output .
