Highlights:
Here are the six key concepts that can be discussed in the prolog assignment:
- Rules
- Facts
- Variables
- Queries
- Line segments
- Backtracking
If you are struggling to comprehend it, then the below-mentioned details with examples can explain it.
Logic programming is the development of systematic procedures to resolve a particular problem. Just like a master chef who combines various ingredients to make delicious recipes, a programmer applies logic to logical code. Hence, writing a prolog assignment will help them practice various coding logic to achieve desired results.
Programming has a reputation of being one of the most difficult subjects to master. For instance, you need to understand the logical statements to write code. So, if you are inefficient in understanding abstract ideas, the programming can give you a hard time. Therefore, writing an assignment will address these concerns.
In this article, we will write about key concepts in the prolog that you must know before writing any assignment on programming. Keep reading if you have trouble grasping certain prolog assignment ideas.
What Are The 6 Basic Concepts You Need to Know for Prolog Assignment?
As we have talked about above, prolog assignments can be difficult. It is associated with the complexity of the subject itself. Also, students fear facing this as they believe they can’t understand the complex formulation and computation. Moreover, they don’t understand the prolog assignment structure well. If you are facing difficulty in writing your programming assignment for similar reasons, then avail yourself of assignment writing services to get it done by professionals.
Keep reading to learn the concepts that form the cornerstone of any programming logic.
1. Facts
Generally, we are aware that facts are objective statements that are mostly considered true. In the prolog, you write a fact by a predicate name followed by the list of arguments written in brackets. Such a statement in a prolog assignment needs to end with the period. However, if a variable occurs in this expression, it is classified as universally quantified.
Example:
Trinity College Presents an example to describe how you can write a fact in a prolog.
2. Rules
Any predicate expression that is a logical implementation to highlight the relation among facts is called a rule. You can simply state to call it a rule. Rather in a prolog assignment, you need to provide some semantic meaning to the statements. In this regard, consider the example below to grasp what is being said.
Example:
Let’s suppose someone “X” is thirsty. So, you will think that “Bar” is the place to go in this situation. To visit any other place, you will follow the rules “go-y”. In the main predicate body, you did not use anywhere thirsty(X). Hence, a good rule in the prolog should sensibly describe the situation. Therefore, it would be more reasonable to include the person itself in the clause.
“Ali should go to the bar if he is feeling thirsty.”
In the programming language, you can write it as,
go_bar(Sam):- thirsty(Sam).
3. Variables
The prolog assignment variable is any values that are not fixed. Rather any of the interpreters can change it depending on the situation. Typically, it is written with an uppercase letter or an underscore. Such prolog variable assignments form the basics of any query that needs to be resolved to satisfy a situation.
Example:
? – cute_doll(X).
You can read this goal as,
‘find the X’s value such that cute_doll(X) is proven.
4. Queries
In any database, the facts and rules are interpreted by the interpreter. These are the queries that are resolved by the experts. It shows what is true about a particular problem and how it can be corrected. Here, you ask the prologue whether the query is true or not. If it is true, the answer is yes by displaying any variable bindings. Moreover, if it fails to resolve the query, then the answer is “No”.
Example:
You can consider any query to resolve in the prolog assignment. For instance,
? – Meal (XX), Dinner (XX). // Which food is meal and dinner?
? – Lunch (Bread Roll). // Is bread roll a lunch?
However, if resolving these queries is not possible for you, even if you have tried several times, then acquire assignment help to find viable answers. Moreover, you can give an example of how such queries can be resolved.
Prolog Assignment Examples:
The University of California San Diego presents an example. One of the assignment questions is given below.
5. Line Segments
Generally, there are three types of line segments that you can mention in the prolog assignment. It may be,
Horizontal Line:
A straight line that starts from left to right or even right to left. For instance, if two points have the same two coordinates on the Y axis, then it comes under “horizon”.
Vertical Line:
A vertical line runs from bottom to top or top to bottom. Usually, it is drawn between the basis of trapezoid or other related figures.
Oblique Lines:
It is a straight line, which is neither vertical nor horizontal. It lies at the oblique angle between the plains, other than the right angle.
Examples:
Pinterest gives the examples below for better illustration.
6. Backtracking
Backtracking is a technique that you use to resolve various queries in a prolog assignment. You can use the combination of facts and rules to logically reason the solutions. It starts with the first clause that matches the queries. As a result, you intend to find satisfying results. If it is proven, it turns into a logical answer. However, if it fails, then you true the next clause. The process goes on unless you reach the appropriate answer.
Example:
The TutorialsPoint presents an example where backtracking is explained like a tree structure.
In this example, the A and G are the facts were starting from A, you want to reach the end goal, which is G.
Prolog Assignment Topics
Usually, students are not front-loaded with topic ideas when studying coursework. Hence, they struggle with finding a good assignment topic. The list below can be helpful in finding a better idea.
- What is Java programming language for creating an app?
- What is the concept of inheritance and polymorphism in programming?
- What are the various programming techniques for computer programs?
- Discuss various aspects of coral programming.
Conclusion
Writing prolog assignments can be nerve-wrenching for many learners. People want to make a career in programming. However, considering the complexity of the subject, they feel mastering it is not under their control. But nothing remains difficult unless you practise the ideas again and again by writing. Assignment writing is better in this regard.
By writing difficult coding logically and analysing the facts, you may able to break down the difficulty. However, if, after extensive practice, you are still not efficient and think of making mistakes in your task, then it is better to look for assignment writing help to get flawless documents. However, even if doing it on your own, then get comprehension of the basics first. Hence, read the above-mentioned concepts explained via example to fulfil the intent. Later on, you can better perform in your assignment paper.
