DETERMINING METHOD OF DIVISION SYMBOL STRING, INFORMATION PROCESSING DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To acquire a division symbol string with high reusability by a smaller division number.SOLUTION: An information processing device 10 includes: a storage unit 11 which stores a plurality of first symbol strings G1 arranging one or more symbols; and an arithmetic logical unit 12. When the first symbol string G1 is expressed using a second symbol string G2 that is a group of consecutive symbols common to the plurality of first symbol strings G1, the arithmetic logical unit 12 selects the second symbol string G2 on the basis of an evaluation index in which evaluation is higher as the number of the first symbol strings G1 containing the same second symbol string G2 is larger and the number of the second symbol strings G2 contained in the first symbol string G1 is smaller.
