Lecture 6 & 7 : O ( log ( n ) / log log ( n ) ) Approximation Algorithms for ATSP
نویسنده
چکیده
In the next few lectures we will talk about three new variants of the classical randomized rounding technique, namely the rounding by sampling method, the pipage rounding method and the iterative rounding method. We will use these techniques to design approximation algorithms for Asymmetric TSP (ATSP) and the Steiner tree problems. The materials of the this lecture are based on the works of Asadpour, Goemans, Madry, Oveis Gharan and Saberi [Asa+10].

An Improved Integrality Gap for Asymmetric TSP Paths
The Asymmetric Traveling Salesperson Path (ATSPP) problem is one where, given an asymmetric metric space (V, d) with specified vertices s and t, the goal is to find an s-t path of minimum length that visits all the vertices in V . This problem is closely related to the Asymmetric TSP (ATSP) problem, which seeks to find a tour (instead of an s-t path) visiting all the nodes: for ATSP, a ρ-approx...
متن کاملA near-optimal approximation algorithm for Asymmetric TSP
5 We present a near-optimal polynomial-time approximation algorithm for the asymmetric 6 traveling salesman problem for graphs of bounded orientable or non-orientable genus. Our al7 gorithm achieves an approximation factor of O(f(g)) on graphs with genus g, where f(n) is the 8 best approximation factor achievable in polynomial time on arbitrary n-vertex graphs. In par9 ticular, the O(log n/ log...
متن کاملAn Almost Linear Time 2.8334-Approximation Algorithm for the Disc Covering Problem
The disc covering problem asks to cover a set of points on the plane with a minimum number of fix-sized discs. We develop an O(n(log n)(log log n)) deterministic time 2.8334-approximation algorithm for this problem. Previous approximation algorithms [7, 3, 6], when used to achieve the same approximation ratio for the disc covering problem, will have much higher time complexity than our algorithms.
متن کاملAdvanced Approximation Algorithms ( CMU 18 - 854 B , Spring 2008 ) Lecture 27 : Algorithms for Sparsest Cut Apr 24 , 2008
In lecture 19, we saw an LP relaxation based algorithm to solve the sparsest cut problem with an approximation guarantee of O(logn). In this lecture, we will show that the integrality gap of the LP relaxation is O(logn) and hence this is the best approximation factor one can get via the LP relaxation. We will also start developing an SDP relaxation based algorithm which provides an O( √ log n) ...
متن کاملApproximation Algorithms for the Asymmetric Traveling Salesman Problem : Describing two recent methods
The paper provides a description of the two recent approximation algorithms for the Asymmetric Traveling Salesman Problem, giving the intuitive description of the works of Feige-Singh[1] and Asadpour et.al [2]. [1] improves the previous O(log n) approximation algorithm, by improving the constant from 0.84 to 0.66 and modifying the work of Kaplan et. al [3] and also shows an efficient reduction ...
