ejpam-4629	Kalampakas, Antonios	Graph Automata and Graph Colorability	2023	9	.pdf	application/pdf	3554	178	71	Engelfriet and Vereijken, in [7], presented an algorithm that inductively constructs every graph G ∈ GR(Σ) from the set Σ ∪ {Π, I01, I21, I10, I12, } by using graph product and graph sum. Math, 16 (1) (2023), 112-120 118 where graph product and graph sum are denoted, for simplicity, by horizontal and vertical concatenation.	cache/ejpam-4629.pdf	txt/ejpam-4629.txt
