Computing Planar Convex Hulls with a Promise

Sepideh Aghamolaei, Kevin Buchin, Timothy M. Chan +5

Computing the convex hull of a planar -point set is one of the most fundamental problems in computational geometry. It has an lower bound in the algebraic comp…

Massively-Parallel Heat Map Sorting and Applications To Explainable Clustering

Sepideh Aghamolaei, Mohammad Ghodsi

Given a set of points labeled with labels, we introduce the heat map sorting problem as reordering and merging the points and dimensions while preserving the clusters (labels).…

A 2-Approximation Algorithm for Data-Distributed Metric k-Center

Sepideh Aghamolaei, Mohammad Ghodsi

In a metric space, a set of point sets of roughly the same size and an integer are given as the input and the goal of data-distributed -center is to find a subset of s…

A Massively Parallel Dynamic Programming for Approximate Rectangle Escape Problem

Sepideh Aghamolaei, Mohammad Ghodsi

Sublinear time complexity is required by the massively parallel computation (MPC) model. Breaking dynamic programs into a set of sparse dynamic programs that can be divided, solved…

An Efficient Construction of Yao-Graph in Data-Distributed Settings

Sepideh Aghamolaei, Mohammad Ghodsi

A sparse graph that preserves an approximation of the shortest paths between all pairs of points in a plane is called a geometric spanner. Using range trees of sublinear size, we d…

Clustering Geometrically-Modeled Points in the Aggregated Uncertainty Model

Vahideh Keikha, Sepideh Aghamolaei, Ali Mohades +1

The -center problem is to choose a subset of size from a set of points such that the maximum distance from each point to its nearest center is minimized. Let $Q=\{Q_1,\l…

Computing The Packedness of Curves

Sepideh Aghamolaei, Vahideh Keikha, Mohammad Ghodsi +1

A polygonal curve with vertices is -packed, if the sum of the lengths of the parts of the edges of the curve that are inside any disk of radius is at most , for…

Catching a Polygonal Fish with a Minimum Net

Sepideh Aghamolaei

Given a polygon in the plane that can be translated, rotated and enlarged arbitrarily inside a unit square, the goal is to find a set of lines such that at least one of them al…

A Data-Structure for Approximate Longest Common Subsequence of A Set of Strings

Sepideh Aghamolaei

Given a set of strings , their longest common subsequence (LCS) is the string with the maximum length that is a subset of all the strings in . A data-structure for this p…

Symmetries: From Proofs To Algorithms And Back

Sepideh Aghamolaei

We call an objective function or algorithm symmetric with respect to an input if after swapping two parts of the input in any algorithm, the solution of the algorithm and the outpu…

Point-Location in The Arrangement of Curves

Sepideh Aghamolaei, Mohammad Ghodsi

An arrangement of curves in the plane is given. The query is a point and the goal is to find the face of the arrangement that contains . A data-structure for point-locat…

Approximating The p-Mean Curve of Large Data-Sets

Sepideh Aghamolaei, Mohammad Ghodsi

A set of piecewise linear functions, called polylines, each with at most vertices can be simplified into a polyline with vertices, such that the Fréche…

A Composable Coreset for k-Center in Doubling Metrics

Sepideh Aghamolaei, Mohammad Ghodsi

A set of points in a metric space and a constant integer are given. The -center problem finds points as centers among , such that the maximum distance of any poin…
