A solution was given by B. L. Fox in 1975 in which the k-shortest paths are determined in O(m + kn log n) asymptotic time complexity (using big O notation. [5] In 1998, David Eppstein reported an approach that maintains an asymptotic complexity of O ( m + n log n + k ) by computing an implicit representation of the paths, each of which can be ...

Bitbucket Server (formerly known as Stash [18]) is a combination Git server and web interface product written in Java and built with Apache Maven. [19] It allows users to do basic Git operations (such as reviewing or merging code, similar to GitHub ) while controlling read and write access to the code.
The windy postman problem is a variant of the route inspection problem in which the input is an undirected graph, but where each edge may have a different cost for traversing it in one direction than for traversing it in the other direction. In contrast to the solutions for directed and undirected graphs, it is NP-complete. [11] [12]
The Viterbi algorithm is named after Andrew Viterbi, who proposed it in 1967 as a decoding algorithm for convolutional codes over noisy digital communication links. [2] It has, however, a history of multiple invention, with at least seven independent discoveries, including those by Viterbi, Needleman and Wunsch, and Wagner and Fischer. [3]

A solution to the relaxed problem is an approximate solution to the original problem, and provides useful information. The method penalizes violations of inequality constraints using a Lagrange multiplier, which imposes a cost on violations. These added costs are used instead of the strict inequality constraints in the optimization.
