Landete, M., Sainz-Pardo, J.L. (2022) “The Domatic Partition Problem in Separable Graphs”, Mathematics, 10 (4):640

Mercedes Landete and José Luis Sainz-Pardo (Operations Research Center, University Miguel Hernández of Elche)
Abstract: The domatic partition problem consists of partitioning a given graph into a maximum number of disjoint dominating sets. This problem is related with the domatic number problem, which consists of quantifying this maximum number of disjoint dominating sets. Both problems were […]
