A (1+)-approximation algorithm for 2-line-center
We consider the following instance of projective clustering, known as the 2-line-center problem: Given a set S of n points in R2, cover S by two congruent strips of minimum width. Algorithms that find the optimal solution for this problem have near-quadratic running time. In this paper we present an algorithm that, for any ε > 0, computes in time O(n(logn+ ε−2 log(1/ε))+ ε−7/2 log(1/ε)) a cover...
متن کاملA Constant Approximation Algorithm for Scheduling Packets on Line Networks
In this paper we improve the approximation ratio for the problem of maximizing the throughput of line networks with bounded buffers. Each node in the network has a local buffer of bounded size B, and each edge (or link) can transmit a limited number c of packets in every time unit. The input to the problem consists of a set of packet requests, each defined by a source node, a destination node, ...
متن کاملA hybrid algorithm for the path center problem
Let a graph G = (V;E) be given. In the path center problem we want to find a path P in G such that the maximum weighted distance of P to every vertex in V is minimized. In this paper a genetic algorithm and ahybrid of genetic and ant colony algorithms are presented for the path center problem. Some test problems are examined to compare the algorithms. The results show that for almost all exampl...
متن کاملA 2 2/3 Superstring Approximation Algorithm
Given a collection of strings S = fs 1 ; : : : ; s n g over an alphabet , a superstring of S is a string containing each s i as a substring; that is, for each i, 1 i n, contains a block of js i j consecutive characters that match s i exactly. The shortest superstring problem is the problem of nding a superstring of minimum length. The shortest superstring problem has applications in both data c...
متن کامل2 . 2 A 78 - Approximation Algorithm for MAX 3 SAT
In CS109 and CS161, you learned some tricks of the trade in the analysis of randomized algorithms, with applications to the analysis of QuickSort and hashing. There’s also CS265, where you’ll learn more than you ever wanted to know about randomized algorithms (but a great class, you should take it). In CS261, we build a bridge between what’s covered in CS161 and CS265. Specifically, this lectur...
