Jun 10, 2008 · good old D1 hey!! what you have to do is make a minimum spanning tree of the network without using one node and the arcs connected to it, in the exam they will always tell you which node to delete, so remove it an scribble out all the arcs attched to it.
3-opt - Wikipedia
https://en.wikipedia.org/wiki/3-opt
In optimization, 3-opt is a simple local search algorithm for solving the travelling salesman problem and related network optimization problems. 3-opt analysis involves deleting 3 connections (or edges) in a network (or tour), to create 3 sub-tours. Then the 7 different ways of reconnecting the network are analysed to find the optimum one.

https://brilliant.org/wiki/matching-algorithms/
Matching algorithms are algorithms used to solve graph matching problems in graph theory. A matching problem arises when a set of edges must be drawn that do not share any vertices. Graph matching problems are very common in daily activities. From online matchmaking and dating sites, to medical residency placement programs, matching algorithms are used in areas spanning scheduling, …
