Abstract Bipartite graphs are of great importance in many real-world applications. Butterfly, which is a complete $$2 \times 2$$ 2 × biclique, plays key role bipartite graphs. In this paper, we investigate the problem efficient counting number butterflies. The most adva...

The development of connected and autonomous vehicles opens an opportunity to manage intersections without signals. One promising approach is use a central intersection manager optimize the movement in intersection. Existing work uses Mixed Integer Linear Programming (MILP) find optimal solutions for this problem but time-consuming cannot be applied real-time. On other hand, coordination essenti...
