One interesting branch of Mathematics that was exclusively developed for the purpose of applications to other field is Graph theory. More specifically, graph colouring is an important tool in designing models for practical applications. The main focus of this Volume 3 is on Snake graph families. The AUM Block coloring and Power dominator coloring of Quadrilateral Snake graphs, Alternate Quadrilateral Snake graphs, Double Quadrilateral Snake graph, Alternate Double Quadrilateral Snake graphs and also Cyclic Snake related graphs such as Cyclic Snake graphs, Alternate Cyclic Snake graphs are obtained. The interesting quantifyable parameters namely, AUM Block chromatic number and Power dominator chromatic number are determined for these snake graph families. This notable contribution will be very much helpful to the aspiring researchers in Mathematics and Applied fields. Such graph theoretical tools serve as solution providers to many real life, practical problems, in varied fields like communication network, data mining, web designing, image processing, agricultural crops plantation pattern etc.
