Abstract: This paper presents a new dual network simplex algorithm for the minimum cost network flow problem. The algorithm works directly on the original capacitated network and runs in O(mn(m + n log n) log n) time for the network with n nodes and m arcs. This complexity is better than the complexity of Orlin, Plotkin and Tardos' (1993) dual network simplex algorithm by a factor of m/n. .
