Game Chromatic Number of Shackle Graphs [PDF]

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika), 2021
Coloring vertices on graph is one of the topics of discrete mathematics that are still developing until now. Exploration Coloring vertices develops in the form of a game known as a coloring game. Let G graph.

The game chromatic number of trees and forests [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
While the game chromatic number of a forest is known to be at most 4, no simple criteria are known for determining the game chromatic number of a forest. We first state necessary and sufficient conditions for forests with game chromatic number 2 and then

Game chromatic number of lexicographic product graphs [PDF]

open access: yesAKCE International Journal of Graphs and Combinatorics, 2015
In this paper, we determine the exact values of the game chromatic number of lexicographic product of path P2 with path Pn, star K1,n and wheel Wn. Also we give an upper bound for the game chromatic number of lexicographic product of any two simple ...

Bears with Hats and Independence Polynomials [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
Consider the following hat guessing game. A bear sits on each vertex of a graph $G$, and a demon puts on each bear a hat colored by one of $h$ colors. Each bear sees only the hat colors of his neighbors.

Game-Perfect Semiorientations of Forests

open access: yesDiscussiones Mathematicae Graph Theory, 2022
We consider digraph colouring games where two players, Alice and Bob, alternately colour vertices of a given digraph D with a colour from a given colour set in a feasible way. The game ends when such move is not possible any more.

On kernels in strongly game-perfect digraphs and a characterisation of weakly game-perfect digraphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
We prove that the game-perfect digraphs defined by Andres (2012) with regard to a digraph version of the maker-breaker graph colouring game introduced by Bodlaender (1991) always have a kernel.

Line game-perfect graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
The $[X,Y]$-edge colouring game is played with a set of $k$ colours on a graph $G$ with initially uncoloured edges by two players, Alice (A) and Bob (B). The players move alternately. Player $X\in\{A,B\}$ has the first move. $Y\in\{A,B,-\}$.

Note On The Game Colouring Number Of Powers Of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2016
We generalize the methods of Esperet and Zhu [6] providing an upper bound for the game colouring number of squares of graphs to obtain upper bounds for the game colouring number of m-th powers of graphs, m ≥ 3, which rely on the maximum degree and the ...
