查询词典 bipartite

By itself consists of the second part of this thesis, which provides adetailed discussion of the so-called finite-time disentanglement in bipartite sys-tems first introduced by Yu and Eberly. The results show that this phenomenonis due to the energy transfer between the system and its surroundings or dueto the internal energy transfer.

This article studies the Microsoft Game-Freecell. It applies the Pigeonhole Principle, Ramsey Principle, Bipartite Graphs Principle to approve the maximum available space to complete the game successfully under random sorting. It introduces the specific algorithms that can archive the goal successfully under the game rules. It also presents the calculation of permutation under this algorithm by adopting the Mobius Inversion and Inclusion-Exclusion principle.
