Research ArticleOpen accessIn the keywordsEdge Double-Critical GraphsJohn J. LattanzioProblem statement: The vertex double-critical conjecture that the only vertex double-critical graph is the complete graph has remained unresolved for over forty years. The edge analogue of this conjecture has been proved. Approach: It was observed that if the chromatic number decreases by two upon the removal of a 2-matching, then the 2-matching comprises four vertices which determine an induced … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,452 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGraph Coloring Program of Exam Scheduling Modeling Based on Bitwise Coloring Algorithm Using PythonSamsul Arifin, Indra Bayu Muktyas, Wikky Fawwaz Al Maki, Mohd Khairul Bazli Mohd AzizA graph coloring is the process of assigning labels to the vertices of a graph in such a way that no two adjacent vertices have the same color. The chromatic number of a graph G is the smallest number of colors that can be assigned to it. Graph coloring has a wide range of applications and is commonly used to … …Journal of Computer Science, Vol. 18, Issue 1 · 1 Feb 2022 · 9,702 accessesView PDF Cite
