Abstract
The present invention concerns a method of sorting objects in N passes into R receptacles. The method includes the following steps: PA0 recording information comprising N criteria per object, PA0 classifying the objects in memory in a given order, so as to assign each of the objects to a destination, PA0 calculating the distribution of the objects in a (N-1)'th canonical pass to assign all of the objects that have the same values of a first criterion to the same receptacle, PA0 calculating the distribution in an N'th canonical pass to assign all the objects that have the same value of a second criterion to the same receptacle in the given order, PA0 modifying the distribution of said N'th canonical pass, to provide a modified distribution of the N'th pass such that each receptacle contains P objects at the most, (P being the maximum contents of each receptacle), PA0 determining the contents of each receptacle at the end of a provisional (N-1)'th pass, performed in such a manner as to allow the modified distribution of the N'th pass, PA0 modifying the distribution of the N'th modified pass, providing a definitive distribution of the N'th pass, if the contents of a receptacles of the…
