partition problem

With these three operations, many practical partitioning problems can be solved (see the Applications section).

This article is about the heuristic algorithm for the graph partitioning problem.

For generalizations of the partition problem, see the Bin packing problem.

Secondly, they developed an algorithm that finds an optimum solution for the partition problem in time.

Such partition problems have been discussed in literature as bicriteria-approximation or resource augmentation approaches.

In the partition problem, the goal is to partition S into two subsets with equal sum.

Typically, graph partition problems fall under the category of NP-hard problems.

In mathematics, the multi-level technique is a technique used to solve the graph partitioning problem.

A related problem is the partition problem, a variant of the knapsack problem from operations research.

The 3-partition problem is similar to the partition problem, which in turn is related to the subset sum problem.

More complex partitioning problems (i.e. 3 or more phases present) can sometimes be handled with a fugacity capacity approach.

Balanced matrices are important in linear programs such as the set partitioning problem, as they are naturally integer.

Contrary to the graph partition problem, the partitions output by computing the strength are not necessarily balanced (i.e. of almost equal size).

For a heuristic algorithm for the graph partitioning problem, see Kernighan-Lin algorithm.

Recently, the uniform graph partition problem has gained importance due to its application for clustering and detection of cliques in social, pathological and biological networks.

If the 3-partition instance can be solved, then (k, 1)-balanced partitioning problem in G can be solved without cutting any edge.

In contrast, the partition problem is known to be NP-complete only when the numbers are encoded in binary, and have value exponential in n.

However, there are variations of this idea that are fully polynomial-time approximation schemes for the subset-sum problem, and hence for the partition problem as well.

One interesting special case of subset sum is the partition problem, in which s is half of the sum of all elements in the set.

The inclusion exclusion principle forms the basis of algorithms for a number of NP-hard graph partitioning problems, such as graph coloring.

However, uniform graph partitioning or a balanced graph partition problem can be shown to be NP-complete to approximate within any finite factor.

A modern transcription has been published by Calzoni and Cavazzoni (1996) as well as a partial translation of the chapter on partitioning problems (Heeffer, 2010).

Clustering ensemble (Strehl and Ghosh): They considered various formulations for the problem, most of which reduce the problem to a hyper-graph partitioning problem.

The weighted version of the decision problem was one of Karp's 21 NP-complete problems; Karp showed the NP-completeness by a reduction from the partition problem.
