We propose a novel algorithm for the hierarchical clustering of graphs. The algorithm is a simple but key modification of the Louvain algorithm based on some sliding-resolution scheme. In particular, the most relevant clusterings, corresponding to different resolutions, are identified. The algorithm is parameter-free, fast and memory efficient. Numerical experiments on both synthetic and real datasets show the performance of the algorithm.
