- The travelling purchaser problem, the vehicle routing problem and the ring star problem are three generalizations of TSP.
- The decision version of the TSP belongs to the class of NP-complete problems.
- Thus, it is possible that the worst-case running time for any algorithm for the TSP increases superpolynomially with the number of cities.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Travelling salesman problem article was read about 270,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 84 and blocks with 84: each hit it takes is cut by 34 %.
