第一篇:数学建模集训的编程队员,请看这篇日志

如果你是数学建模集训的编程队员,请看这篇日志

黄冈职院 数学建模协会 编程部顾青山

首先,你们都很优秀。学东西很快,熬夜的能力也不错,当然,除非非常时刻,我们不推荐后者。集训这么长时间,我觉得有必要整理一些小tips 跟你们分享。

1、有空不要玩游戏或做无关的事,那会影响你们组队员的团结,他们嘴里面不说,但是还是有一点介意的,谁叫你们是一个团队,就应该相互负责。你可以选择,看别人的程序,有时候你的编程的语句用法,不一定是最优的,你可以在看别人的程序过程中,学到很多东西

2、心平气和,不宜烦躁,程序报一天的错,或是一个小时还没运行出结果,这是很正常的,不要觉得程序在运行,你就可以看电影、打游戏。你可以选择继续检查程序的思路,跟建模的人商量更细节的算法,或把你干的事讲给写作的人听。总之,千万别停下!

3、不想受苦的话,跟建模和写作的队友交流。建模的人头脑一热,想出一个完美的模型,可是你可能用几天是编不出来 的,那么你就应该提出,稍微简化的思路,如果有时间,再进一步的完善。还有,把你干的事,告诉写作的,否则,评委通过你们的论文很难看出你干了什么惊天伟地的事的。那不是很悲催么?!

4、跟其它编程的人交流,封闭是无法让你走的更远的。

以下是技术篇:

1、不要频繁的从excel中读取写入文件,那会影响速度,你可以选择,用.mat文件保存起来,下载它的速度会快一些。

2、确保变量名的前三十一个字符是独一无二的,否则,MATLAB 将辨认不出两变量的不同

3、如果变量名与MATLAB 中的函数或命令重名,那么这个函数或命令将不能被访问

4、不要创建和MATLAB 内建函数或命令同名的M 文件。

5、直接强行退出会导致数据丢失,先用save保存,然后再quit退出。6、对于大小写敏感问题,请统一用小写表示变量

7、强调过很多遍,不要用纯数字和汉字来命名M文件,铁定报错,命名一定要遵从自己的习惯,有条理,否则到了决赛的时候,你都弄不清楚哪一个程序是对应哪一问,哪个是修改版哪个是先编的。

8、如果有库函数,就可以节省自己的时间,直接调用吧,不要自己重编了,现在是比赛,时间极为有限。比如要将n个字符串连在一起,可以用cat,而不用一个一个敲,往后排,别这样:['stud

y', 'see','good','...']

9、如果用点乘可以解决的,就别用for循环了,当问题规模大的时候,这点小区别是很致命的。这也是为什么同一个问题,差不多的思路,有的人的程序需运行5分钟,而有的人只需要1秒,前者用了元胞cell,后者用矩阵,前者没有结构化,后者从头到尾都会优化结构。

10、非常重要的一点,一问做完了,及时把结果保存,以txt或者mat保存都可以。不要觉得所有问题都做完后再整理结果交给写作的队友,很明确的告诉你,当问题多达5或6问后,这么做就是一个灾难,到最后困扰的还是自己和队友。

第三篇:数学建模集训个人总结

数学建模集训个人总结

数学,一直是我比较热衷的科目。数学建模也是数学的一种,但它却有别于数学。数学建模更贴近实际,是一门把数学知识同实际问题紧紧联系的学问,它可以让我们体会怎么样把数学理论与实际生活相结合。因此我便对数模有了浓厚的兴趣,并有志向在方面发展。参加数学建模竞赛是我的一个计划。在大学的第一个暑假,我很高兴参加了数学建模集训,这次集训让我充实了自己。

数学建模竞赛是本科生接触实际科学问题的第一步,是利用所学书本知识、广泛涉猎课外知识、利用数学和计算机工具、为某一具体问题建立抽象模型、给出求解方法并解决问题、最后撰写论文并给出客观评价的一个系统工程。数学建模就是利用数学知识对一些实际问题建立模型,但又不是纯数学的。它不仅要数学思维,还计算机编程能力、论文写作能力有一定的要求。其实更重要的是团队协作能力,这对我们以后工作、生活都有非常大的作用。

在这个炎热的暑假里,我们学校的老师、同学们都还留在学校奋战着。我们学校的数学建模集训分成了两个阶段。由本校毛老师和曹老师,姚老师还有总校的杜老师授课。时间为一个月。短暂的时间里,老师传授了我们很多数学的知识及相关软件运用,如图论,运筹学,优化论等知识,和matlab,lingo,spss等软件。虽然也只是短短的一个月,但在这短暂的时间里,老师教了我们很多建模和论文写作的精髓,这些让我受益匪浅,并对数学建模有了新的认识,更有了强大的动力和支持。

在这一个月的学习中,我最大的收获可能就是,我更深层次的了解了数学建模,了解了自己的不足,体会到团结合作的那种精神。同时在平时的课余时间里,我也结识了一些学习高手,结伴共战。初始时,对于大一的我,数学建模是神秘的,我觉得那是一件很高深的事情。从各种数学知识的积累,到各类软件的运用;从整体性思维,到对每一处细节的分析;数学建模这个词语,对每位新人,都是如此的玄妙。这个暑假我们几乎是在实验室里度过的,“痛并快乐着”,学到的不仅仅是实际的知识,更重要的是一种思维——分析,解决问题的一种思维。

数学建模让我在奋斗中领会了这样的一个道理“想象力比知识重要,因为知识是有限的,而想象力概括着世界的一切,推动着社会科技的进步,并且是知识的源泉。”在本次数学建模集训解决问题时,我觉得充分发挥想象力和联想能力,从而将一个问题看成另一个问题,才能将问题比较容易地解决的。数学建模竞赛作为一种竞赛,它真的给了我们很多的锻炼机会。首先是敏锐的洞察力、丰富的想象力的培养。其次是创新能力真正得到了锻炼。创新能力在数学建模的过程中体现的淋漓尽致。它需要我们利用自己已有的知识和经验,在坚强的个性品质支持下,新颖而独特地提出问题、分析问题、解决问题,并由此产生有价值的新思想、新方法、新成果。而且让我们在应试教育摇篮中成长起来的大学生平生第一次感觉到了素质教育的魅力和美丽。建 模的过程中没有老师的讲解,更不是书本上的知识的生搬硬套,建模真正地强化了学生主体地位,体现了创造性学习的力量。

我认为数学建模之所以拥有如此神奇的教育能力是因为它尝试了两个模式:(1)探索讨论。这种方法让我们自己探索新知识,注重独立钻研, 建模创造了一种环境,在这种环境中我们可以自由的提出一些问题、通过自学解决问题、老师只是与我们共同探讨。在这几天的学习过程中老师选择了合适的问题,通过情景、问题引导、激发我们的学习和讨论,真正达到了教育学生的目的而我们也在不知不觉中学会了很多东西。(2)团队形式和论文写作。老师将我们分成若干小组,指定问题,而我们也真正的体会到了要解决问题就必须努力地学习阅读相关的参考文献并相互讨论,在查找资料的过程中我们进行着激烈的讨论为的是形成一个解决问题的方案,通过计算给出结果,并写出完整的论文。这样的模式充分发挥我们每个学生的特长,如计算、分析、编程、写作等,并使我们养成与别人合作工作的良好习惯。

数学建模真正地将我们的数学知识及其它知识, 与现实世界交汇在某一点上了。在这些天的探索学习过程中,我们建模创造, 反过来数学建模也促进了我们的学习。努力实践,不断探索, 共同奋斗让我们三个人在短短的培训时间里, 将没有规律的数据, 现实的现象,化为一个我们可以驾御的数学问题并完成一篇属于我们的论文。

这次暑假数学建模集训对我这么一个大一的学生来说是一次难忘的经历,因为我真的学到很多知识,体验到很多快乐。我坚信下次集训我一定会继续参加,继续奋战的!
