Methods for partionning a set of objects and method for searching in a partition of a set of objects

摘要

Method for partitioning an object collection comprises an initialization phase for determining a partition having an optimal number of classes and a modification phase for this partition in order to obtain a partition in which the classes have an optimum content from the point of view of finding objects. Independent claims are made for (1) a multilevel partition method for a collection of objects using the preceding method to create a hierarchical structure. (2) a computer program (3) equipment of the means of storage and processing of data
