Abstract :

Biological networks have recently gathered much attraction in finding their motifs, which are small connected sub-graphs that occur significantly in higher frequencies than in random networks. They are useful concept to uncover structural design principles of complex networks. The importance of this problem causes attention of improving the existing algorithms. As the running time of an algorithm is an important aspect, applying parallel techniques is appropriate for better improvement. In this paper we present a parallel algorithm (ParaKavosh) for finding motifs. We evaluated our algorithm on biological networks of E. coli, S. cerevisiae, Homo sapiens and Rattus norvegicus. The optimality of our algorithm is demonstrated by comparing the obtained results with an efficient sequential algorithm. The results show that our algorithm performs much better in terms of running time.
