We study the concept of an -partition of the vertex set of a graph , which includes all vertex partitioning problems into four parts which we require to be nonempty with only external constraints according to the structure of a model graph , with the exception of two cases, one that has already been classified as polynomial, and the other one remains unclassified. In the context of more general vertex-partition problems, the problems addressed in this paper have these properties: non-list, -part, external constraints only (no internal constraints), each part non-empty. We describe tools that yield for each problem considered in this paper a simple and low complexity polynomial-time algorithm.
