by Klaus Jansen
(
Book
)
15 editions published in 2002 in English and held by 307 WorldCat member libraries worldwide This book constitutes the refereed proceedings of the Third International Workshop on Approximation Algorithms for Combinatorial Optimization Problems, APPROX 2000, held in Saarbrcken, Germany in September 2000. The 22 revised full papers presented together with four invited contributions were carefully reviewed and selected from 68 submissions. The topics dealt with include design and analysis of approximation algorithms, inapproximibility results, online problems, randomization techniques, averagecase analysis, approximation classes, scheduling problems, routing and flow problems, coloring and partitioning, cuts and connectivity, packing and covering, geometric problems, network design, and various applications

Online algorithms for weighted bipartite matching and stable marriages
by Samir Khuller
(
Book
)
3 editions published between 1990 and 1991 in English and held by 8 WorldCat member libraries worldwide Abstract: "We give an online deterministic algorithm for the bipartite weighted matching problem that achieves a competitive ratio of O(n). In fact, this algorithm is almost optimal  the lower bound on the performance ratio of any deterministic online algorithm is [omega](n/[square root of log n]). We also study the stable marriage problem, where we are interested in the number of unstable pairs produced. We show that the simple 'first come, first served' deterministic algorithm yields on the average O(n log n) unstable pairs, but in the worst case no deterministic or randomized online algorithm can do better than [omega](n²) unstable pairs."
Dynamics of three degree of freedom kinematic chain
by Berthold Horn
(
Book
)
3 editions published in 1977 in English and held by 7 WorldCat member libraries worldwide In order to be able to design a control system for highspeed control of mechanical manipulators, it is necessary to understand properly their dynamics. An analysis is presented here of a detailed model of a threelink device which may be viewed as either a leg in a locomotory system, or the first three degrees of freedom of an arm providing for its gross motions. The equations of motion are shown to be nontrivial, yet manageable

Solving the weighted parity problem for gammoids by reduction to graphic matching
by Po Tong
(
Book
)
1 edition published in 1982 in English and held by 5 WorldCat member libraries worldwide It is shown that the weighted parity problem for gammoids, with matching and transversal matroids as special cases, can be reduced to the weighted graphic matching problem. Since the cycle matroid of a series parallel graph is a gammoid, this means that it is possible to solve the weighted parity problem for the cycle matroid of a series parallel graph by graphic matching

Random polynomial time is equal to semirandom polynomial time
by Umesh V Vazirani
(
Book
)
2 editions published in 1988 in English and held by 4 WorldCat member libraries worldwide We prove that any onesided error random polynomial time (RP) algorithm can be simulated with a semirandom source at no more than polynomial factor loss in efficiency. i.e. RP=SRP. This contrasts with the fact that a semirandom source is too weak to simulate fair coin flips [SV]
The twoprocessor scheduling problem is in random NC
by Umesh Virkumar Vazirani
(
Book
)
2 editions published in 1989 in English and held by 4 WorldCat member libraries worldwide Abstract: "An efficient parallel algorithm (RNC[superscript 2]) for the twoprocessor scheduling problem is presented. An interesting feature of this algorithm is that it finds a highest level first schedule: such a schedule defines a lexicographically first solution to this problem in a natural way. A key ingredient of the algorithm is a generalization of a theorem of Tutte which establishes a onetoone correspondence between the bases of the Tutte matrix of a graph and the sets of matched nodes in maximum matchings in the graph."
Processor efficient parallel algorithms for the two disjoint paths problem, and for finding a Kuratowski homeomorph
by Samir Khuller
(
Book
)
1 edition published in 1989 in English and held by 3 WorldCat member libraries worldwide We give an $NC$ algorithm for finding vertex disjoint $s_{1}, t_{1}$ and $s_{2}, t_{2}$ paths in an undirected graph $G$. An important step in solving the general problem is solving the planar case. A new structural property yields the parallelization, as well as a simpler linear time sequential algorithm for this case. We extend the algorithm to the nonplanar case by giving an $NC$ algorithm for finding a Kuratowski homeomorph, and, in particular, a homeomorph of $K_{3}, 3$, in a nonplanar graph. Our algorithms are processor efficient; in each case, the processortime product of our algorithms is within a polylogarithmic factor of the best known sequential algorithm

Pfaffian orientations, 0/1 permanents, and even cycles in directed graphs
by Vijay V Vazirani
(
Book
)
2 editions published in 1987 in English and held by 3 WorldCat member libraries worldwide The following issues in computational complexity remain imprecisely understood: the striking difference in the complexities of computing the permanent and determinant of a matrix despite their similar looking formulae, the complexity of checking if a directed graph contains an even length cycle, and the complexity of computing the number of perfect matchings in a graph using Pfaffian orientations. Via polynomial time equivalences, we show interrelationships among these issues
Efficient sequential and parallel algorithms for maximal bipartite sets
by David Pearson
(
Book
)
2 editions published in 1991 in English and held by 3 WorldCat member libraries worldwide Abstract: "A maximal bipartite set (MBS) in an undirected graph G = (V, E) is a maximal collection of vertices B [contained as subclass within] V whose induced subgraph is bipartite. In this paper we present efficient sequential (linear time) and parallel (NC) algorithms for constructing an MBS."
