||This article needs attention from an expert on the subject. The specific problem is: "This page is very poor in terms of contents. No pseudo-code, scarce references. This algorithm deserves a lot better description and treatment.". (September 2016)|
3-opt analysis involves deleting 3 connections (or edges) in a network (or tour), reconnecting the network in all other possible ways, and then evaluating each reconnection method to find the optimum one. This process is then repeated for a different set of 3 connections.
