Problems solved by technology

[0009] The present invention mainly solves the problems existing in the prior art that it is difficult to find out the relationship between two sets of discrete data, and it is impossible to judge their similarity and correlation, and provides a method that can quickly judge two sets of data Mutual mapping relationship, a method of establishing a two-way mapping between sequence of numbers under the condition of difference limit to explore their correlation and similarity

Embodiment

[0027] Example: such as image 3 Shown, the present invention is a kind of method that establishes two-way mapping between sequence under the condition of difference limit, it is characterized in that it comprises the following steps:

[0028] ⅰ Put two groups of data in the computer storage space, which are respectively SeqA and SeqB, and arrange SeqA and SeqB in the two comparison modules in order from small to large, forming two series of numbers SepX and SepY, each data of the series The item occupies a location in the comparison module, and the location where the data item is stored is called the effective location;

[0029] ⅱ Establish two data item cursor variable modules CurX, CurY, initialize CurX to point to the last data item of SeqX, initialize CurY to point to the last effective location of SeqY;

[0030] ⅲ Discriminate the two data items pointed to by CurX and CurY, obtain the difference Diff of the two data items pointed to by CurX and CurY, and set the differe...

Abstract

The invention relates to a method for establishing bi-directional mapping among sequences under the condition of difference limitation. According to the method for establishing bi-directional mapping among sequences under the condition of difference limitation, two groups of discrete data are arranged into two sequences from small to large respectively, the two sequences are stored in two comparison modules, are pointed in sequence and compared through data item vernier variable modules CurX and CurY, if two data which meet the condition of difference limitation and are respectively located in the two sequences exist, a bi-directional mapping relation is established and stored, finally data items with the bi-directional mapping relation in the two sequences are counted, and therefore the purposes of discovering the relevance and similarity of the two groups of data are achieved.

Description

[0001] technical field [0002] The invention relates to a software technology, in particular to a method for establishing a two-way mapping relationship by comparing and analyzing numbers. [0003] Background technique [0004] Sequence: A sequence of numbers arranged in a certain order is called a sequence of numbers. Each number in the sequence is called a data item of the sequence, or item for short. . [0005] Bidirectional mapping: A bidirectional pointing relationship between two data items. The bidirectional mapping in the present invention specifically refers to: (1) The two data items of the bidirectional mapping must belong to two different sequence; (2) When any data item has become an item in a certain bidirectional mapping, it must not become another One item in the two-way mapping, that is, there must be no overlap between the two-way mappings; (3) The difference between the two numbers of the previous item and the next item of any two-way mapping should m...
