P-sets and Data Internal Search-application
YU Xiu-qing · 2011
Introduced by dynamic characteristics,P-sets can be obtained from the improved finite general sets.P-sets are a set pair which are composed of internal P-sets X and outer P-sets XF,or(X,XF) is P-sets.By using P-sets,the concept of data internal search,the measure and dependence relation about-data were given,search iterative algorithm and criterion of-data were proposed,finally the applications of data internal search were given.P-sets is a new theory and method to study dynamic information system.
