Largest and Smallest Area Triangles on Imprecise Points
Vahideh Keikha, Maarten Löffler, Ali Mohades
Assume we are given a set of parallel line segments in the plane, and we wish to place a point on each line segment such that the resulting point set maximizes or minimizes the are…
Fast Frechet Distance Between Curves With Long Edges
Joachim Gudmundsson, Majid Mirzanezhad, Ali Mohades +1
Computing the Fréchet distance between two polygonal curves takes roughly quadratic time. In this paper, we show that for a special class of curves the Fréchet distance computation…
Special Guards in Chromatic Art Gallery
Hamid Hoorfar
We present two new versions of the chromatic art gallery problem that can improve upper bound of the required colors pretty well. In our version, we employ restricted angle guards…
Maximum-Area Quadrilateral in a Convex Polygon, Revisited
Vahideh Keikha, Maarten Löffler, Ali Mohades +2
In this note we show by example that the algorithm presented in 1979 by Dobkin and Snyder for finding the largest-area k-gon that is inscribed in a convex polygon fails to find the…
Improper Filter Reduction
Fatemeh Zahra Saberifar, Ali Mohades, Mohammadreza Razzazi +1
Combinatorial filters have been the subject of increasing interest from the robotics community in recent years. This paper considers automatic reduction of combinatorial filters to…
