Notes about assignments:

二人小组可协力完成并缴交单一组家庭作业。

部分习题以奇数编号，并且可从Orlin教授的网页取得(http://web.mit.edu/jorlin/www/)。您的责任是在谘询网站之前先努力的解答奇数编号习题, 并且确保任何一篇报告是完全出自于您。请不要直接地采用网站上的措词。同样规则适用于其他您可以取得解答的习题。如果您为了解决习题而谘询了其他解答, 请在您的报告中提及这件事。

每份家庭作业将以总分3分的标准来评分，如教学大纲所描述。评分者将彻底评分部分习题，并且简要地审视其他部分。

Groups of two may collaborate and hand in a single homework set.

Some of the exercises are odd numbered, and are available from Professor Orlin's home page (http://web.mit.edu/jorlin/www/). You are on your honor to give the odd numbered exercises a sincere effort before consulting the web site, and to make sure that any write-up is fully your own. Please do not use phrasing taken directly from the web site. The same rule applies to any other problem to which you may have access to a solution. If you consulted another solution in order to solve the exercise, please mention this in your write-up.

Homework will be graded out of 3 points, as described in the syllabus. The grader will fully grade some exercises, and briefly scan others.
