二维限邻排列的初步探究

Preliminary Exploration of Two-dimensional Limit Adjacent Arrangement

本文研究二维限定相邻元素的排列问题,由单组的限邻问题推广多组限邻问题,其中多次用到容斥原理、集合的交并运算和归纳与猜想原理,得到一些比较好的结果.

This paper mainly studies the limit of adjacent element permutation problem,by a single set of limited promotion group limited adjacent problems,which often uses including-excluding principle,intersection and union operation of sets and principle of induction and conjecture,get some good results.
