Algorithms for approximate FSM traversal

Proceedings of the 30th international on Design automation conference - DAC '93, 1993
In this paper we present algorithms for approximate FSM traversal based on state space decomposition. The original FSM is partitioned in sub-machines, and each of them is traversed separately; the result is an over-estimation of the set of reachable states. Several traversal strategies are discussed.

Approximate Traveling Salesman Algorithms

Operations Research, 1980
There have been a multitude of heuristic algorithms proposed for the solution of large scale traveling salesman problems. Our intent in this paper is to examine some of these well known heuristics, to introduce some new heuristics, and to compare these approximate techniques on the basis of efficiency and accuracy.

Greedy in Approximation Algorithms

2006
The objective of this paper is to characterize classes of problems for which a greedy algorithm finds solutions provably close to optimum. To that end, we introduce the notion of k-extendible systems, a natural generalization of matroids, and show that a greedy algorithm is a 1/k-factor approximation for these systems.

An Algorithm for Approximate Tandem Repeats

Journal of Computational Biology, 2001
A perfect single tandem repeat is defined as a nonempty string that can be divided into two identical substrings, e.g., abcabc. An approximate single tandem repeat is one in which the substrings are similar, but not identical, e.g., abcdaacd. In this paper we consider two criterions of similarity: the Hamming distance (k mismatches) and the edit ...

Dynamic Algorithms for Approximating Interdistances

2003
Summary: We present efficient dynamic algorithms for approximation of \(k\)th, \(1\leq k\leq{n\choose 2}\) distance defined by some pair of points from a given set \(S\) of \(n\) points in \(d\)-dimensional space. Our technique is based on the dynamization of well-separated pair decomposition proposed in [\textit{P. B. Callahan} and \textit{S.

Approximation Algorithms for the Achromatic Number

Journal of Algorithms, 2001
Summary: The achromatic number for a graph \(G=\langle V,E \rangle\) is the largest integer \(m\) such that there is a partition of \(V\) into disjoint independent sets \(V_1,\dots,V_m\) such that for each pair of distinct sets \(V_i\), \(V_j\), \(V_i\cup V_j\) is not an independent set in \textit{G.

Approximation algorithms for graph augmentation

Journal of Algorithms, 1992
Summary: The problem of increasing both edge and vertex connectivity of a graph at an optimal cost is studied. Since the general problem is NP-hard, we focus on efficient approximation schemes that come within a constant factor from the optimal. Previous algorithms either do not take edge costs into consideration, or they run slower than our algorithm.
