AB  - We consider the symmetric traveling salesman problem (TSP) with instances represented by complete graphs with distances between cities as edge weights. Computational experiments with randomly generated instances on 50 and 100 vertices with the
uniform distribution of integer edge weights in interval [1, 100] show that there exists a correlation between the sequences of the spectral radii of the distance matrices and the lengths
of optimal tours obtained by the well known TSP solver Concorde. In this paper we give a
partial theoretical explanation of this correlation.
