Calculating topological indices of certain OTIS interconnection networks

Abstract

Abstract Recently, increasing attention has been paid to The Optical Transpose Interconnection System (OTIS) network because of its prospective applications in architectures for parallel as well as distributed systems [27, 28]. Different interconnection networks in the context of topological indices are researched recently in [25, 26]. This article includes the computions of the general Randi´c, first and second Zagreb, general sum connectivity, first and second multiple zagreb, hyper zagreb, ABC and GA indices for OTIS (swapped and biswapped) networks by taking path and k -regular graph on n vertices as a base graphs. In addition, some delicated formulas are also obtained for the ABC 4 and GA 5 indices for the OTIS biswapped networks by considering basis graph as a path and k -regular graph of order n .
