Speech Title: A fuzzy graph approach to interconnection networks

Abstract: In most of the modern interconnection networks like internet, the reduction of flow between different nodes is more frequent than the disruption of the entire network. Majority of the classical graph theoretical parameters were dealing with disconnections alone. The introduction of fuzzy logic by Zadeh, paved the way for fuzzy graph theory, which mainly concerned with strength reducing sets rather than disconnecting sets. Partial cutnodes and partial bridges respectively represent cutvertices and bridges in fuzzy graphs, whose removal reduce the strength of connectedness between different pairs of nodes of a network. Determination of partial cutnodes and partial bridges in a fuzzy graph is still a difficult task. There was a gradual development in the field of interconnection networks, using fuzzy graph theory in the last 20 years. Different theoretical and algorithmic aspects of networks will be studied in a fuzzy graph framework in the presentation.
