In this paper, we discussed five cases with respect to branching decisions based on network solutions to calculate the nearest link with a short time. From the results, bound and branch algorithm can develop and change the obtaining solutions for the five cases under study.}, number={4}, journal={Al-Mustansiriyah Journal of Science}, author={Elaibi, Waleed Mohammed}, year={2020}, month={Dec.}, pages={114–119} }
