Game Chromatic Number of Graphs
, 1998 We show that if a graph has acyclic chromatic number k, then its game chromatic number is at most k(k + 1). By applying the known upper bounds for the acyclic chromatic numbers of various classes of graphs, we obtain upper bounds for the game chromatic ...

Exploring Unknown Environments
, 1997 . We consider exploration problems where a robot has to construct a complete map of an unknown environment. We assume that the environment is modeled by a directed, strongly connected graph.

Ramsey-Type Results for Oriented Trees
, 2007 . For a graph G and a digraph ~ H, we write G! ~ H (respectively, G a ! ~ H) if every orientation (respectively, acyclic orientation) of the edges of G results in an induced copy of ~ H. In this note we study how small the graphs G such that G!

Open MathematicsLet T(X) be a full transformation semigroup on a nonempty set X. The Cayley digraph Γ of a semigroup T(X) with respect to the Green’s L $\mathcal{L}$ -class is a digraph with vertex set T(X) and two vertices α, β ∈ T(X) are adjacent as an arc (α, β ...
