A computer program is a sequential set of instructions written in a computer language that is used to direct the computer to perform a specific task of computation.

Observe that the definition demands that any set of instructions must be such that the tasks will usually be performed sequentially unless directed otherwise. Each instruction in the set will express a unit of work that a computer language can support. In general, high level languages, also known as 3GLs, support one human activity at a time. For example, if a computational task involves the determination of the average of three numbers, then it will require at least three human activities, viz., getting the numbers, obtaining the sum of the numbers, and then obtaining the average. The process will therefore require three instructions in a computer language. However, it can be done using two instructions, also: first by obtaining the numbers and second by obtaining the sum and the average.

The objective of programming is to solve problems using computers quickly and accurately.

A problem is something the result of which is not readily available. A set of steps involving arithmetic computation and/or logical manipulation is required to obtain the desired result. There is a law called the law of equifinality that states that the same goal can be achieved through different courses of action and a variety of paths, so the same result can be derived in a number of ways. For example, consider the task of sending a message to one of your friends. There are many ways in which this can be done. First, you can convey the message over the phone if your friend possesses a phone. Second, you can send it by post. Third, you can send it through a courier service. If the message is urgent, then you can try to use the quickest means for sending it. If it is not urgent, then you will choose to send it in the least expensive but most reliable way of doing it. Depending upon the urgency, you will decide the most effective way of doing it. This most effective way is called the optimum way. The different ways of solving a problem are called solution strategies. The optimum way of solving a problem to get the desired result can be achieved by analyzing different strategies for the solution and then selecting the way that can yield the result in the least time using the minimum amount of resources. The selection process will depend on the efficiency of the person and his/her understanding of the problem. He/she must also be familiar with different problem-solving techniques. Determining the set of steps required to solve a given problem is an art. It shows how well a person can arrange a set of steps so that others can follow it. A type of analysis called task analysis is required to reach the solution from a problem definition that states what is to be achieved.

A set of steps that generates a finite sequence of elementary computational operations leading to the solution of a given problem is called an algorithm. An algorithm may be too verbose to follow. The textual description of an algorithm may not be understood quickly and easily. This is why a pictorial representation may be used as a substitute for an algorithm. Such a pictorial representation is called a flowchart. Formally speaking, a flowchart is a diagrammatic representation of the steps of an algorithm. In a flowchart, boxes of different shapes are used to denote different types of operations. These boxes are then connected by lines with arrows denoting the flow or direction to which one should proceed to know the next step. The connecting lines are known as flow lines. Flowcharts may be classified into two categories:
(i) Program Flowchart
(ii) System Flowchart

CS代写|程序设计作业代写algorithm Programming代考|Program flowcharts

Program flowcharts act like mirrors of computer programs in terms of flowcharting symbols. They contain the steps of solving a problem unit for a specific result.

System flowcharts contain the solutions of many problem units together that are closely related to each other and interact with each other to achieve a goal. We will first focus on program flowcharts.

A program flowchart is an extremely useful tool in program development. First, any error or omission can be more easily detected from a program flowchart than it can be from a program because a program flowchart is a pictorial representation of the logic of a program. Second, a program flowchart can be followed easily and quickly. Third, it serves as a type of documentation, which may be of great help if the need for program modification arises in future.
The following five rules should be followed while creating program flowcharts.

  • Only the standard symbols should be used in program flowcharts.
  • The program logic should depict the flow from top to bottom and from left to right.
  • Each symbol used in a program flowchart should contain only one entry point and one exit point, with the exception of the decision symbol. This is known as the single rule.
  • The operations shown within a symbol of a program flowchart should be expressed independently of any particular programming language.
  • All decision branches should be well-labeled.
    The following are the standard symbols used in program flowcharts:

Flowcharts can be used to show the sequence of steps for doing any job. A set of simple operations involving accepting inputs, performing arithmetic operation on the inputs, and showing them to the users demonstrate the sequence logic structure of a program. The following flowchart shows the steps in cooking rice and then utilizing the cooked rice.
The algorithm for the flowchart about cooking rice is as follows:
Step 1. Take the rice to be cooked.
Step 2. Procure the container.
Step 3. Procure the water.
Step 4. Wash the rice in the water.
Step 5. Put the rice into the container.
Step 6. Pour water into the container.

请注意,该定义要求任何指令集必须使得任务通常按顺序执行,除非另有指示。集合中的每条指令都将表达计算机语言可以支持的一个工作单元。通常,高级语言(也称为 3GL)一次支持一项人类活动。例如,如果一项计算任务涉及确定三个数字的平均值,那么它将需要至少三个人类活动,即,获取数字,获取数字的总和,然后获取平均值。因此,该过程将需要计算机语言中的三个指令。但是,也可以使用两条指令来完成:第一个是获取数字,第二个是获取总和和平均值。

  • 在程序流程图中只能使用标准符号。
  • 程序逻辑应该描述从上到下和从左到右的流程。
  • 程序流程图中使用的每个符号应仅包含一个入口点和一个出口点,但决策符号除外。这被称为单一规则。
  • 程序流程图符号中显示的操作应该独立于任何特定的编程语言来表达。
  • 所有决策分支都应该有良好的标签。

术语 广义线性模型(GLM)通常是指给定连续和/或分类预测因素的连续响应变量的常规线性回归模型。它包括多元线性回归,以及方差分析和方差分析(仅含固定效应)。



有限元是一种通用的数值方法,用于解决两个或三个空间变量的偏微分方程(即一些边界值问题)。为了解决一个问题,有限元将一个大系统细分为更小、更简单的部分,称为有限元。这是通过在空间维度上的特定空间离散化来实现的,它是通过构建对象的网格来实现的:用于求解的数值域,它有有限数量的点。边界值问题的有限元方法表述最终导致一个代数方程组。该方法在域上对未知函数进行逼近。[1] 然后将模拟这些有限元的简单方程组合成一个更大的方程系统,以模拟整个问题。然后,有限元通过变化微积分使相关的误差函数最小化来逼近一个解决方案。





随机过程,是依赖于参数的一组随机变量的全体,参数通常是时间。 随机变量是随机现象的数量表现,其时间序列是一组按照时间发生先后顺序进行排列的数据点序列。通常一组时间序列的时间间隔为一恒定值(如1秒,5分钟,12小时,7天,1年),因此时间序列可以作为离散时间数据进行分析处理。研究时间序列数据的意义在于现实中,往往需要研究某个事物其随时间发展变化的规律。这就需要通过研究该事物过去发展的历史记录,以得到其自身发展的规律。


多元回归分析渐进(Multiple Regression Analysis Asymptotics)属于计量经济学领域,主要是一种数学上的统计分析方法,可以分析复杂情况下各影响因素的数学关系,在自然科学、社会和经济学等多个领域内应用广泛。
