PIP PATTERN PRODUCING DEVICE FOR BINGO SHEET, PIP PATTERN PRODUCING PROGRAM FOR BINGO SHEET, AND METHOD OF PRODUCING PIP PATTERN FOR BINGO SHEET

摘要

PROBLEM TO BE SOLVED: To produce pip patterns, while maintaining the variety, for a bingo sheet in a prescribed number fair to participants with a value of expectation for the timing of occurrence of desired "bingo" in a bingo sheet with any one of a plurality of kinds of limited events to actually occur sequentially in a time series with different probabilities of occurrence being assigned to each pip of the bingo sheet. SOLUTION: A pip pattern producing part 62 produces pip patterns of a next generation in the same number as a prescribed number of pip patterns according to the genetic algorithm. A pip changing part 63 changes any one pip in a pip pattern to another pip with the similar probability of occurrence. An evaluating part 65 evaluates the prescribed number of pip patterns collectively based on the position in the time series where the "bingo" occurs by applying the data on the events stored in a data storage device 11 to the prescribed number of pip patterns along the time series. An updating part 66 makes the pip pattern updated by sections 62 and 63 till a prescribed evaluation is obtained. COPYRIGHT: (C)2005,JPO&NCIPI
