Reconstructing 3-Colored Grids from Horizontal and Vertical Projections Is NP-hard
We consider the problem of coloring a grid using k colors with the restriction that in each row and each column has an specific number of cells of each color. In an already classi...

Connected Coloring Completion for General Graphs: Algorithms and Complexity
An r-component connected coloring of a graph is a coloring of the vertices so that each color class induces a subgraph having at most r connected components. The concept has been w...

A characterization of uniquely vertex colorable graphs using minimal defining sets
A defining set (of vertex coloring) of a graph G is a set of vertices S with an assignment of colors to its elements which has a unique completion to a proper coloring of G. We de...

Minimum sum set coloring of trees and line graphs of trees
In this paper, we study the Minimum Sum Set Coloring (MSSC) problem which consists in assigning a set of x(v) positive integers to each vertex v of a graph so that the intersectio...

Conditional Adaptive Star Grammars
Abstract. The precise specification of software models is a major concern in model-driven design of object-oriented software. In this paper, we investigate how program graphs, a la...
