The common people does everything possible to need to be grasping its evidence that can be got hold of in lawsuits or arguments , can claim indemnity one, evidence that can be got hold of in lawsuits or arguments does not also need to set aside bone , the bone should not also be very many set aside ice; Reporter who has chosen bone with a covetous look that is to big news having speculation value absolutely , the problem does not also need to create problem, in that USA does not become a problem's filter oil powder having arrived at China is a problem, being put into use filtering oil powder is pinker than being needless to filter oil also being problem , nonutility therefore in the homeland the eatery is fundamental, that the common people knows this neither is what thing.

老百姓想方设法要抓着它的把柄，可以索赔它一笔，没有把柄也要挑出骨头，没有骨头也要挑出冰太多；记者虎视眈眈谁挑着了骨头那绝对是有炒作价值的大新闻，没有问题也要创造问题，在美国不成为问题的滤油粉到了中国那就是个问题，使用滤油粉比不用滤油粉更是个问题，所以国内餐馆基本不用，老百姓也不了解这是个什么东西。

In the real life, have some to grow similarity since new problem and the old problem are general, unknown object and the known number object get in touch with always mutually, be on basis observing carefully in new problem , overwear knowledge , come to handle the new problem old experience, this thought is that process it is have purpose's , effective conversion contradiction, to solve a problem ultimately change solving problems that process , the mathematics inscribe one kind , is to change from saying , solving problems on this significance melt return to

中文摘要：在实际生活中，由于新老问题总有某种相似之处，未知的事物与已知的事物总是相互联系的，即在新问题仔细观察的基础上，用旧知识、旧经验来处理新问题，这种思维是一种转化过程，数学题的解题过程就是有目的的、有效的转化矛盾，最终解决问题，从这个意义上说，解题就是转化。

Based on the study on the traveling salesman problem, in this dissertation, some results on the solving of production scheduling problem using the neural networks are described, which includes the following main parts: l The method which was put forward by Hopfield－Tank of solving the traveling salesman problem is analyzed, and the drawbacks of the method are pointed out.

Thirdly, we examine a job scheduling problem, in which jobs could be processed by multiple in-line steppers. This problem includes two decisions: job assignment and job sequencing. Through developing a new and concise representation scheme for modeling the two decisions, we solve the multiple-machine scheduling problem by various meta-heuristic algorithms. The preceding single-machine scheduling problem in fact is a special case of the multiple-machine scheduling problem.
