2. Construction Heuristics A construction heuristic is an algorithm that determines a tour according to some construction rules, but does not try to improve upon this tour. A tour is successively built and parts already built remain unchanged throughout the algorithm. A detailled discussion of construction heuristics can be found in .

A tour construction heuristic constructs the tour from scratch, beginning with one city and iteratively expanding the subtour by one city at a time. In contrast, a tour improvement heuristic begins with a complete tour and makes one or more rearrangements in an attempt to improve it.Author: Ziauddin Ursani, David W. Corne

The construction heuristics discussed so far build a complete tour by iteratively extending a connected partial tour. An alternative approach is to iteratively build several tour fragments that are ultimately patched together into a complete tour. One example for a construction heuristic of this type is the Greedy Heuristic, which works as follows.

Aug 24, 1999 · The tour construction heuristic that generates initial tours for the tour improvement heuristics plays an important role in solving the travelling salesman problem (TSP). With the help of an effective tour construction heuristic, the performance of a heuristic can be improved. In this study we present a new tour construction algorithm, the construction priority (CP).Cited by: 8

Less Flexibility First(LFF) principle is inspired and developed by enhancing some rule-of-thumb guidelines resulting from the generation-long work experience of human professionals in ancient days. In this paper, we generalize this principle to the classical Traveling Salesman Problem and propose a tour construction heuristic. Our new heuristic is closely...Cited by: 1

Nov 01, 2004 · The proposed heuristic narrows the performance gap between the class of tour construction and tour improvement heuristics. The performance of the proposed method improves as the instance size increases, but runtime grows quadratically for Euclidean instances and cubically for non-Euclidean instances.

This is the only tour construction heuristic which will guarantee a noncrossing tour for points in the plane. Tour Improvement Heuristics Two-opt: This heuristic systematically looks at each pair of nonadjacent edges of the current tour and determines whether the tour length would be decreased by removing these two edges and adding the other ...
