A. Chakraborti, The euclidean travelling salesman problem: Frequency distribution of neighbors for small-size systems, INT J MOD C, 12(6), 2001, pp. 857-863
We have studied numerically the frequency distribution p(n) of the nth neig
hbor along the optimal tour in the Euclidean travelling salesman problem fo
r N cities, in dimensions d = 2 and d = 3. We find there is no significant
dependence of p(n) on either the number of cities N or the dimension d.
