An algorithm is a finite set of sequential instructions that one should perform in order to solve a well-formulated problem. Algorithms have a lot of advantages. In computer programming, It is a sequence of computational procedure that takes a collection of elements or values as input and produce a collection of elements or values as output.
What is the Definition of An Algorithm?
An algorithm may be a concept that examines problems employing a series of instructions and mathematical and logical analysis and provides an appropriate solution for it. In other words, an algorithm may be a step-by-step thanks to solving a drag.
The algorithm helps us to bring the matter solving steps closer to the pc language and eventually Turn it into comprehensible code. the tactic of calculating the mark average in class is the example of the algorithm.
What is An Algorithm In Computer Science?
An algorithm is a representation of a step-by-step procedure to solve a problem. An algorithm in computer science is a series of precise steps for solving a problem in a finite amount of time. It is better to write an algorithm before writing the actual computer program because it saves time.
Characteristics of An Algorithm
All algorithms must meet the subsequent conditions and criteria:
An algorithm must accept none or more parameters as input;
The algorithm must produce a minimum of one quantity as output (the result of operation);
Algorithm commands must be expressed in precise, unambiguous language. Any instructions must be followed. Commands like “Add 6 or 7 to x” or “Calculate 5 to zero” aren’t allowed; Because within the first example, it’s not clear what number should be chosen, and within the second example, division by zero isn’t defined in mathematics.
The algorithm must have a particular beginning and end, in order that if we follow its instructions, for all cases, the algorithm ends after browsing a variety of steps. additionally, the time required to finish the algorithm must be reasonably short.
Algorithm Examples In Everyday Life
Now let’s check out an example of an algorithm that a lot of folks have certainly acted on by now. For example, suppose we would like to write down the steps to travel to college step by step!
- Waking up
- Washing hands and face
- Having breakfast
- Wear appropriate clothing
- Removing the specified equipment (books and…)
- Leaving home
- Go to university
- Enter the category
What is clear is that these commands must be executed so as, otherwise, there’s an opportunity of error, so are the pc algorithm.
Advantages of Algorithms
According to the Capital Markets press agency (Sena), one of the foremost important benefits of algorithmic trading is trading without the intervention of human emotions and prejudices. But the opposite benefits of those deals are:
1- Lower Transaction Cost
Algorithms are designed to figure with minimal impact on the market. This suggests that the investor can sell at a better price and patronize a lower cost.
2- Information Security
In the process of transferring a buy or sell order to traders, information could also be disclosed which will usually increase transaction costs. Disclosing bulk buying or selling information may encourage the market to shop for or sell, which can cause prices to fluctuate.
3- Intangible Movements
Some of the codes of successful fund managers or investors are monitored by marketers. Algorithms behave far more complexly. For instance, a manager decides to shop for a stock, but the market can’t realize this thanks to the frequent and daily trading algorithm on the stock and therefore the lack of shopping for and selling excitement.
4- More Accuracy
Algorithms will always execute commands tirelessly and without mistakes. during this sort of transaction, the danger of individual mistakes decreases and market access increase
Properties of Algorithm
Following are some properties of an algorithm:
- A particular problem should be broken down into easy and meaningful steps
- Number these steps also in a sequence
- All steps should be expressive and written in easy English
Here, it is also important to know about Pseudo-code.
Pseudo Code Test?
Algorithms are written in a language, which is similar to simple English. This language is known as pseudo-language. Pseudo-code is used to state program logic in an English-like style that is independent of any specific programming language. This simplifies program development by separating it into two main parts:
- Logical Design
In this part, the logic of the program is designed. We specify different steps required to solve the problem and also the sequence of these steps.
In this part, the algorithm is converted into a program. All the steps of the algorithm are also converted into commands of any programming language.
The use of pseudo-code enables the programmer to concentrate on the planning of the program. After the planning is final, it can be written in any programming language.
The following algorithm accepts two numbers from the user, calculates their sum, and then displays the result.
- Input A, B
- Total =A+B
- Display Total
Advantage and Disadvantage of Algorithm
Following are the most important pros and cons of algorithms in programming:
|Advantages of Algorithm
|Disadvantages of Algorithm
|It uses a specific procedure.
|Time consume process.
|A step-wise representation Of a solution is a specified problem, which makes it easy to understand.
|Difficult to show and Looping.
|Every step – own logical sequence
|Big tasks are difficult to put in algorithms.
|Not dependant on any programming language, so it easy to understand.
|It is written in simple language.
|Provide an easier way for programmers to convert it into an actual program
More Advantages of Algorithms
Some advantages of using pseudo-code to specify algorithms rather than immediately writing programs code are:
When the programmer writes the algorithm and program separately, it would ease the overall job by dividing it into two simpler tasks. Furthermore, while writing the algorithm, we can concentrate on the solution to the problem instead of concentrating on a specific language.
In order to write the code in any language, the programmer writes an algorithm. An algorithm enables the programmer to write the program in any language such as Visual Basic, Java or C++, etc. It is one of the topmost advantages of algorithms
Ease of Understanding
You don’t have to understand a particular programming language to understand an algorithm. Because the programmer writes it in an English-like manner.
