WebOct 1, 2024 · While the branch-and-cut algorithm proposed in Archetti et al. (2016) was able to solve only 25 out of the 64 small instances, the branch-price-and-cut (BPC) algorithm proposed in Archetti et al. (2015) was able to solve all the small instances within the same time limit, and other instances with up to 40 customers and three commodities. WebDec 1, 2024 · In addition, the branch-price-and-cut algorithm is combined with an adaptive large neighborhood search to obtain approximation solutions for large-scale instances. In the computational experiments, instances with up to 50 customers are solved to optimality, and approximation solutions of large-scale instances with 100 customers are presented.
