Polyhedral studies on the convex recoloring problem
(ElsevierAmsterdam, 2013-11-05)
A coloring of the vertices of a graph G is convex if, for each assigned color d, the vertices with color d induce a connected subgraph of G. We address the convex recoloring problem, defined as follows. Given a graph G and ...

SPATIAL VARIABILITY OF THE PROPERTIES OF COHESIVE SOILS FROM EASTERN MARANHAO, BRAZIL
(Soc Brasileira De Ciencia Do Solo, 2014-07-01)
The national and international demand for maps of soil properties has increased. The aim of this study was to characterize cohesive soils and associate their variability of particle size, chemical properties, and color to ...
Computing the coarseness with strips or boxes
(Elsevier, 2017)
Recently, the concept of coarseness was introduced as a measure of how blended a 2-colored
point set S is. In the definition of this measure, a convex partition Π, that is, a partition
of S into sets {S1, . . . , Sk} of ...
