##### 941 An Improved Method to Compute Sparse Graphs for Traveling Salesman Problem

**Authors:**
Y. Wang

**Abstract:**

*O*(

*CN*

_{max}

*n*

^{2}) where

*C*is the iterations,

*N*

_{max}is the maximum number of frequency quadrilaterals containing each edge and

*n*is the scale of TSP. The experimental results showed the computed sparse graphs generally have less than 5

*n*edges for most of these Euclidean instances. Moreover, the maximum degree and minimum degree of the vertices in the sparse graphs do not have much difference. Thus, the computation time of the methods to resolve the TSP on these sparse graphs will be greatly reduced.
