An imprecise point is a point p with an associated imprecision region Ip indicating the set of possible locations of the point p. We study separability problems for a set R of red imprecise pointsâ€¦ (More)

Given a set R of red points and a set B of blue points in the plane, we study the problem of determining all angles for which there exists an L-shape containing all points from B and no points fromâ€¦ (More)

Let S be a set of n imprecise points in the plane that each imprecise point is modeled by a segment. In this paper, we study the problem of finding a minimum perimeter convex hull of S that segmentsâ€¦ (More)

Given a set R of red points and a set B of blue points in the plane of total size n, we study the problem of determining all angles for which there exists an L-shape containing all points from Bâ€¦ (More)
