We consider the problem of ranking assignments according to cost in the classical linear assignment problem. An algorithm partitioning the set of possible assignments, as suggested by Murty, is presented where, for each partition, the optimal assignment is calculated using a new reoptimization technique.
GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Sign up Murty's Algorithm for m-best assignments; Implementation inspired by Miller's pseudocode (see code).An algorithm for Ranking All the Assignments in Order of Increasing Cost. Publication Type: Journal Article. Authors: Katta G. Murty.In this paper, we show how Murty’s ranked linear assignment algorithm can be applied to exactly solve the symmetric Traveling Salesman Problem (TSP). To increase the Murty algorithm’s computational efficiency in solving the TSP, we develop a simple algorithm that determines whether a node that is generated in Murty’s sequential node partitioning process contains a sub-cycle of length.
Although the Ranking algorithm is sequential, because of the sequential on-line consideration of the outputs, a hardware implementation of the algorithm could exploit parallelism: outputs can issue a Grant in parallel, but they can make their final decision after receiving the match of the preceding output(s), using a method analogous to the carry calculation of a carry-look-ahead adder.

Google’s Panda Algorithm. Panda began as its own stand-alone algorithm which was designed to determine the quality of the content on webpages, among other things. It seeks to determine the quality of the content (how unique it is compared to other content on the web) in order to reduce the duplication of content in the SERPs.
Abstract.In this paper a variant of Murty’s algorithm for ranking assignments according to cost is presented. It is shown that the worst-case computational complexity is better in this variant than in the original form of the algorithm. Computational results comparing three methods for ranking assignments are reported. They show that the behaviour of the new variant is also better in practice.
Though information retrieval algorithms must be fast, the quality of ranking is more important, as is whether good results have been left out and bad results included. The appropriate search algorithm often depends on the data structure being searched, and may also include prior knowledge about the data.
