*k*-Colorings”, Technical Report CS-2000-08, Department of Computer Science, University of Waterloo, March 2000. **Abstract**:-
While discrepancy theory is normally only studied in the context of
2-colorings, we explore the problem of
*k*-coloring, for*k*≥ 2, a set of vertices to minimize imbalance among a family of subsets of vertices. The*imbalance*is the maximum, over all subsets in the family, of the largest difference between the size of any two color classes in that subset. The*discrepancy*is the minimum possible imbalance. We show that the discrepancy is always at most 4*d*− 3, where*d*(the “dimension”) is the maximum number of subsets containing a common vertex. For 2-colorings, the bound on the discrepancy is at most max {2*d*− 3, 2}. Finally, we prove that several restricted versions of computing the discrepancy are NP-complete. **Length**:- The paper is 11 pages.
