Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a hardware algorithm to solve the maximum clique problem of large graphs, and show its implementation results using a dynamically partially reconfigurable FPGA.
Although existing hardware algorithms cannot solve the problem for graphs with many nodes due to the resource limitation on an FPGA, the proposed algorithm can solve the problem for such large graphs using only one FPGA by generating subgraphs from a given graph, and implementing them using dynamically partial reconfiguration of an FPGA.
Since the proposed hardware algorithm is based on a branch-and-bound method, it can explore solution space efficiently, and reduce the number of partial reconfigurations of FPGA.
Our experimental results using a dynamically partially reconfigurable FPGA show that the proposed algorithm can efficiently solve the problem that an existing algorithm cannot solve.
