Travelling Salesman Problem (TSP) is eminent in combinatorial optimization problem. A typical problem in computational mathematics, scientific and business application such as VLSI chip design, social network analysis. TSP, combinatorial optimization problem belongs to the class of NP-Hard, and becomes significant method of verifying the correctness and feasibility of new algorithm. With the accuracy results and efficient cutting branch strategy of branch and bound algorithm, it used to solve TSP. However, branch and bound algorithm not suitable for large scale TSP with sequential execution. In this paper parallel branch and bound algorithm has been improved and proposed to solve the symmetric TSP. This paper uses parallel program code based on multithreading concept to verify TSP. The experimental result shows our algorithm is efficient, and solves the large scale TSP problem which cannot be solved by sequential branch and bound.
