We present an algorithm CRE , which either finds a Hamilton cycle in a graph G or determines that there is no such cycle in the graph. The algorithm's expected running time over input distribution G G (n ,p ) is (1+o (1))n /p , the optimal possible expected time, for urn:x-wiley:rsa:media:rsa20918:rsa20918-math-0001. This improves upon previous results on this problem due to Gurevich and Shelah, and to Thomason.

使用旋转和扩展平均快速找到汉密尔顿周期

我们提出一种算法CRE,该算法要么在图G中找到一个汉密尔顿循环,要么确定图中没有这样的循环。算法的预计在输入分配运行时间ģģÑp)为(1+ Ô(1))ñ / p,最佳可能的预期时间,为骨灰盒:x-wiley:rsa:media:rsa20918:rsa20918-math-0001。由于Gurevich和Shelah以及托马森(Thomason),这改善了先前在该问题上的结果。
