The de Bruijn graph being a regular topology and having structured node connectivity has a small nodal degree. Node placement problem in de Bruijn graph is a combinatorial optimization problem. To exploit the limitless capabilities of lightwave technology, we construct optimized regular multihop network based de Bruijn graph when the traffic flow among the network nodes is asymmetric. Given tha...

We consider the Norton algebra associated with a Q -polynomial primitive idempotent of adjacency matrix for distance-regular graph. obtain formula product that we find attractive.
