Computing simple paths among obstacles
Given a set X of points in the plane, two distinguished points s,t X, and a set of obstacles represented by line segments, we wish to compute a simple polygonal path from s to t...

Decomposing a simple polygon into pseudo-triangles and convex polygons
In this paper we consider the problem of decomposing a simple polygon into subpolygons that exclusively use vertices of the given polygon. We allow two types of subpolygons: pseud...

The Complexity of Subtype Entailment for Simple Types
A subtyping 0 is entailed by a set of subtyping constraints C, written C j= 0, if every valuation (mapping of type variables to ground types) that satisfies C also satisfies 0. ...

Feature Generation by Simple FLD
This paper presents a new algorithm for feature generation, which is approximately derived based on geometrical interpretation of the Fisher linear discriminant analysis. In a fiel...

On the Computation of Colored Domino Tilings of Simple and Non-simple Orthogonal Polygons
We explore the complexity of computing tilings of orthogonal polygons using colored dominoes. A colored domino is a rotatable 2 × 1 rectangle that is partitioned into two unit squ...
