The notion of graphs solvable with finite delay appears in  and . In this note the upper bound on finite delay for a graph with N nodes is reduced to the order of 2<sup>N</sup><sup>2</sup>using techniques from finite automata theory.
Delay of graphs, finite automata theory, graph theory, nondeterministic finite automata, sequential Boolean equations.
