Cost flow algorithm is an optimization algorithm based on graph theory, commonly used to solve network flow problems. In terms of optimizing network bandwidth costs, cost flow algorithms can minimize the bandwidth cost of network flows, thereby maximizing network resource utilization. This article aims to maximize the utilization of network resources by minimizing bandwidth costs in network flows. This algorithm requires calculating the maximum traffic and minimum cost on each path, and iteratively updating the traffic through greedy algorithms and incremental optimization until the optimal solution is found. Compared with traditional linear programming methods, cost flow algorithms not only have higher computational efficiency, but also provide more accurate solu-tions when solving complex network bandwidth optimization problems.
