Polynomial-time algorithm for the orbit problem

Journal of the ACM, 1986
The accessibility problem for linear sequential machines [12] is the problem of deciding whether there is an input x such that on x the machine starting in a given state q 1 goes to a given state q 2 . Harrison shows that

A polynomial time algorithm for subpattern matching

Proceedings of the IEEE, 1986
An O(N3K) time algorithm for searching matches of a template of size K in an image of size N is given. It uses bounding regions and the Soviet Ellipsoid Algorithm [1]. It will work under moderately heavy shift noise.

General Polynomial Time Decomposition Algorithms

2005
We present a general decomposition algorithm that is uniformly applicable to every (suitably normalized) instance of Convex Quadratic Optimization and efficiently approaches the optimal solution. The number of iterations required to be within e of optimality grows linearly with 1/e and quadratically with the number m of variables.

Polynomial-time approximation algorithms for the ising model

SIAM Journal on Computing, 1993
Summary: The paper presents a randomized algorithm which evaluates the partition function of an arbitrary ferromagnetic Ising system to any specified degree of accuracy. The running time of the algorithm increases only polynomially with the size of the system (i.e., the number of sites) and a parameter which controls the accuracy of the result. Further

Markov chains and polynomial time algorithms

Proceedings 35th Annual Symposium on Foundations of Computer Science, 2002
This paper outlines the use of rapidly mixing Markov Chains in randomized polynomial time algorithms to solve approximately certain counting problems. They fall into two classes: combinatorial problems like counting the number of perfect matchings in certain graphs and geometric ones like computing the volumes of convex sets. >

Polynomial time algorithms for network information flow

Proceedings of the fifteenth annual ACM symposium on Parallel algorithms and architectures, 2003
The famous max-flow min-cut theorem states that a source node s can send information through a network (V,E) to a sink node t at a data rate determined by the min-cut separating s and t. Recently it has been shown that this rate can also be achieved for multicasting to several sinks provided that the intermediate nodes are allowed to reencode the ...

A Polynomial Time Algorithm For Fault Diagnosability

25th Annual Symposium onFoundations of Computer Science, 1984., 1984
We present the first polynomial time algorithm for testing t-diagnosability. This is a significant advance in system level fault diagnosis. We also presented part of our analysis of t/s-diagnosability, including the fact that it is co-NP-complete and that there are polynomial algorithms for t/t and t/(t+1)-diagnosability.

A Polynomial Time Algorithm for Shaped Partition Problems

SIAM Journal on Optimization, 1999
Summary: We consider the class of shaped partition problems of partitioning \(n\) given vectors in \(d\)-dimensional criteria space into \(p\) parts so as to maximize an arbitrary objective function which is convex on the sum of vectors in each part, subject to arbitrary constraints on the number of elements in each part.
