## Abstract Star chromatic number, introduced by A. Vince, is a natural generalization of chromatic number. We consider the question, β€œWhen is Ο‡\* < Ο‡?” We show that Ο‡\* < Ο‡ if and only if a particular digraph is acyclic and that the decisioin problem associated with this question is probably not i

In this note, we show that some problems related to the length of the longest simple path from a given vertex in a graph are NP-complete. We also discuss an extension to the graph coloring problem.
