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 [ 2 ].

The Greedy, Quick-Borůvka and Savings Heuristics 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.

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
TOUR CONSTRUCTION HEURISTICS FOR AN ORDER SEQUENCING ...
http://sajie.journals.ac.za/pub/article/view/511
Eight tour construction heuristics are developed and implemented for an order picking system operating in unidirectional picking lines. Two classes of tour construction heuristics the tour construction starting position () and the tour construction ending position () are developed to sequence orders in a picking line.

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.
Match twice and stitch:a new TSP tour construction heuristic
https://vlsicad.ucsd.edu/Publications/Journals/j67.pdf
Tour improvement heuristics start with a valid tour (e.g., the output of a tour construction heuristic [2]) and iteratively improve the tour cost, typically via local search, until some stopping criterion is reached. While tour improvement techniques produce near-optimal tours as measured by the gap from the Held-Karp lower bound [14,15], the solution quality achieved by tour constructions is signicantly …
