英文摘要
We studied the problem of designing low-congestion sparse networks. Especially, we studied the computational complexity of an optimization problem on graphs called “the spanning tree congestion problem.” We presented sharp contrasts between hard cases and easy cases. We also investigated the parameterized complexity of the problem and gave some dichotomies for the problem. Our results imply the problem is really hard to solve for most of the cases. Thus we designed some heuristic and approximation algorithm and obtained some partial results.
