Graph colouring remains a central topic in graph theory, providing the mathematical framework for assigning colours to the elements of a graph under specific constraints. In particular, the colouring ...
The study of graph colouring has long been a central topic in discrete mathematics, with a prominent focus on optimising the assignment of labels or colours to vertices such that adjacent vertices are ...
Abstract: As a new topic attracting research efforts recently, the Wireless Power Transfer based Energy ReDistribution (WPTERD) problem is targeted for finding energy transmission schedules satisfying ...
