Implementation of polygon guarding algorithms for art gallery problems
Shiva Maleki, Ali Mohades
Victor Klee introduce the art gallery problem during a conference in Stanford in August 1976 with that question: "How many guards are required to guard an art gallery?" In 1987, Gh…
PREDICT: Persian Reverse Dictionary
Arman Malekzadeh, Amin Gheibi, Ali Mohades
Finding the appropriate words to convey concepts (i.e., lexical access) is essential for effective communication. Reverse dictionaries fulfill this need by helping individuals to f…
A Time-space Trade-off for Computing the Geodesic Center of a Simple Polygon
Pardis Kavand, Ali Mohades, Mohammad Reza Kazemi
In this paper we study the problem of computing the geodesic center of a simple polygon when the available workspace is limited. For an -vertex simple polygon, we give a time-sp…
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…
