TY - JOUR TI - Packing chromatic number of transformation graphs AU - Doğan Durgun Derya AU - Özen Dörtok H Büşra JN - Thermal Science PY - 2019 VL - 23 IS - 16 SP - 1991 EP - 1995 PT - Article AB - Graph coloring is an assignment of labels called colors to elements of a graph. The packing coloring was introduced by Goddard et. al. in 2008 which is a kind of coloring of a graph. This problem is NP-complete for general graphs. In this paper, we consider some transformation graphs and generalized their packing chromatic numbers.
