Description
In their recent work, I. Banič and A. Taranenko introduced a new notion, the span of a graph. Their goal was to solve the problem of keeping the safety distance while two players are moving through a graph. They presented three different types of graph spans, depending on the movement rules and relating them to the strong, direct and Cartesian graph products. We observed the same goal, but gave a different approach to that problem by directly defining the maximal safety distance for different movement rules two players can take. This allowed us to solve several problems, prove some relations between different graph spans and calculate the span values for some classes of graphs.
