| Outline of Final Research Achievements |
In this work, we developed an algorithm to connect the research results of the Degree/Diameter Program to the Order/Degree Program. It is shown that the ODP can be solved by manually applying the Cayley graph to the ODP, and the results are reported in the IEICE journal. In addition, the graph processing accelerator proposed a data structure for processing graphs in streams, which was presented at the IEICE Technical Committee on Reconfigurable Systems (RECONF). In the development of the graph processing accelerator, it became clear that the calculation of the mean shortest path length ASPL was a problem, but it was not solved. However, with this consideration, a serial approximate adder was invented and a patent was applied.
