Research Term: 2009-2014


The computer has been used for a variety of information processing like optimization/analysis of the industrial process, marketing, and the bioinformatics, etc. For processing the large-scale data that are recently being increased explosively, the importance of not only speeding up of the calculation hardware but also "Algorithm technology", which enable the mathematical condensation and efficient processing of the huge amount of discrete-structured data (represented data of the logical process that the computer does), has been risen. In this project, we deal with two techniques; BDD (Binary Decision Diagram) for manipulating the Boolean functions, and ZDD (Zero-Suppressed BDD: the novel improvement of BDD) for manipulating sets of sparse combinations. We will organize an integrated method of algebraic operations for various types of discrete structures and will investigate the standard techniques for efficiently processing the large-scale practical problems in various fields, including the system verification/optimization, knowledge discovery, statistical analysis, etc.
