  没有一个人的生活道路是笔直的，没有岔道的。有些岔道口，譬如**上的岔道口，事业上的岔道口，个人生活上的岔道口，你走错一步，可以影响人生的一个时期，也可以影响一生。

Strong evidence of a global warming trend exists, and powerful models have been created
to estimate future climate. Temperatures have increased by about 0.5oC over the last 15
years, and global temperature is at its highest level in the past millennium . Although the
warming trend is quite evident, the consequences of such wide scale climate change are
still poorly understood. One of the most-feared consequences of global warming is sea
level rise, and for good reason.

Creating and rating the diculty of Sudoku puzzles is currently a hard computational problem.
In particular, most current approaches require the use of somewhat arbitrary choices for
the relative diculties of Sudoku strategies.
