Weightable and Regular Independent System

  • Received Date: 10 Jun 2006
  • Publish Date: 25 Jun 2007
  • Two combinatorial structures of regular and weightable independent systems were established based on the general cases of multi-key problems.It was proved that a weightable independent system does not contain any inconsistent sets,the independent system without inconsistent sets is the regular independent system,and some regular independent systems contain inconsistent sets.
