摘要
The permutation routing problem is studied for trees under the matching model. By introducing a novel and useful (so-called) caterpillar tree partition, we prove that any permutation on an n-node tree (and thus graph) can be routed in at most 3/2n + O(log n) steps. This answers an open problem of Alon, Chung and Graham.
