数学建模竞赛新手教程(2)建模中的分工与合作------------------------------------------------------------------------------------有些同学觉得，参加数学建模竞赛的目的就是为了提高一下自己的数学水平，或是别的水平，我不以为然。

既然参加数学建模竞赛，其目的就应该是，而且是强烈的目的，去拿一等奖。

-------------------------------------------------------------------------------------我们应该如何分工？传统的标准答案是----数学，编程，写作。

但是对于每一个参加过数学建模竞赛的同学来说，感悟各不相同，所以答案也各不相同。

下面就是我的一家之言，有经验的朋友也可以一起讨论一下。

分工不用那么明确。

但有个前提是大家关系很好。

不然的话，很容易产生矛盾。

提醒一点，在搞竞赛的那几天，睡不好觉，心情急躁，很容易与搭档们发生冲突。

分工太明确了，会让人产生依赖思想，不愿去动脑子。

假如写手只是实现一个打字员的功能，把数模高手的思想表达出来，那是不够的，写手要有自己的思想，能够检查对方的错误，能够提出自己的思想。

按我的想法，理想的分工是这样的。

数学建模竞赛小组中的每一个人，都能胜任其它人的工作，就算小组只剩下她（他）一个人，也照样能够搞定数学建模竞赛。

在竞赛中的分工，只是为了提高工作的效率，做出更好的结果，并不是由于能力不适合做别的工作。

我一直都这么认为，只有能够独当一面的人，才能更好的与他人合作。

其实想想也应该是这样的，在以后的学习、工作、研究中，数学能力、编程能力、论文写作能力，哪一项是可以缺少的呢？当然，现实并非如此。

我们很难找到三个这样的人凑到一起。

所以，凑合着用吧，我给一点儿建议。

三个人中，一定要有一个人脑子比较活，善于思考问题，这个人，嗯，免强归于数学方面吧；一定要有一个人会编程序，能够实现一些算法。
