行运算

We proposed a new method by improving it in a novel way, which can generate pixel of a line row by row according to the first and second row of a line and inherit the advantages of Bresenham algorithm without division and decimal fraction.

This thesis consists of two parts. The first one was that boundary value problem was discrete with five point difference method. Three kinds of memory formats were studied, which were full matrix, half band width and row compress sparse. Full matrix memory format and half band width memory format first was contrasted. The results show that half band width has efficiency in space. Then the algebraic system of finite element method was solved by Gauss-Seidel iteration method to popular row compress sparse memory format.

The reason is many sided: 1 student and parent think " miscalculate " irrespective, as long as next time attentive dot went. The student allows to use a calculator in 2 education, the student had to the calculator depend on, often abandon when encountering seemingly complex calculation think, use a calculator directly, for instance 618, do not know to change brief into 13, achieve a result with the calculator directly however 0.33. Phase of 3 high school trains a student " put forward, analysis and the ability that solve a problem " the demand is higher and higher, of the train of thought that inscribes to solution in classroom education, thoughtway many somes more tuitional, and to operation ability, because the student has certain base, loosened with respect to some then. 4 emphasizes the training of all sorts of thinking ability overly, the training of operation ability has the suspicion that should try education it seems that, this also is one of reasons. The operation in 5 maths, no matter be numeric computation, return be algebraic type to be out of shape figure, photograph of the train of thought that inscribes with new knowledge, new solution, skill is compared and character, appear more as dry as a chip, the student does not have interest.

原因是多方面的：1学生和家长都认为"算错了"没关系，只要下次细心点就行了。2教学中答应学生使用计算器，学生对计算器有了依靠，在碰到貌似复杂的计算时往往舍弃思索，直接用计算器，比如618，不知化简成13，而是直接用计算器获得结果0.33.3高中阶段培养学生"提出、分析和解决新问题的能力"的要求越来越高，课堂教学中对解题的思路、思想方法的讲授多一些，而对于运算能力，因为学生都有一定的基础，于是就有些放松了。4过分强调各种思维能力的练习，运算能力的练习似乎有应试教育的嫌疑，这也是原因之一。5数学中的运算，不管是数值计算，还是代数式的变形演算，和新的知识、新的解题的思路、技巧相比较而言，显得比较枯燥，学生没有喜好。

The arithmetic of the subtraction is based on the serial arithmetic. It can entirely enumerate every pair of subtrahend on a bit, and it also calculates two possible loaning carry values on each bit. So the subtraction can be operated through automatic selection, and complete collateral subtraction and carry operation. The method of single division is same to it. With the stenography of shifengshou we can solve the complex division. We put the formula and the technique into the DNA model to get the result. The methods all make the step decrease and change the conventional arithmetic.

减法的DNA 算法理论主要是来源于串行思路中的算法，它是将每一位上的两个减数对的所有可能进行全列举，同时考虑每一位上的两种借位信息，使得运算进行自动选择，一步即可得到最终结果的算法；除法中一位数除多位数的算法还是从我们平时所进行的串行运算中得到启发而设计的算法；而除法的多位计算思路则来源于史丰收速算法，将算法中的口诀及技巧应用到DNA 链当中，使得传统中的代数运算能够并行的得到最终的结果，这三种算法的设计都使得计算步骤减少，从根本上改变了算法的运算机制。
