![2. DesignProlog clause and rules to check the membership of an element in an list.
Prolog also has a special facility to split the first part of the list. The Head away from the
rest of the list i.e. the Tail. We can place a special symbol | in the list to distinguish
between the first item in the list and the remaining list.
For example,
[first,second,third] = [A|B] where A = first and B= [second,third]
3. Write a Prolog Program to find a factorial of a number.
Formula for calculating n! (Factorial of n) is: n! = n * (n-1)!
We will use two predicates here,
i. Factorial predicate with one argument N, that will calculate and N!
ii. Factorial predicate with two arguments N and F. This function is recursively used. It will
also calculate N!, but store it in the argument F in the process if recursion.](https://image.slidesharecdn.com/artificialintelligence-prologsummary-191103074936/85/Artificial-intelligence-Prolog-8-320.jpg)
Artificial intelligence - Prolog
- 1. Prolog : Prolog is a logic programming language associated with artificial intelligence and computational linguistics. Prolog is intended primarily as a declarative programming language. In prolog, logic is expressed as relations (called as Facts and Rules). Core heart of prolog lies at the logic being applied. Formulation or Computation is carried out by running a query over these relations. It has important role in artificial intelligence. Prolog facts are expressed in definite pattern. Facts contain entities and their relation. Entities are written within the parenthesis separated by comma (, ). Their relation is expressed at the start and outside the parenthesis. Every fact/rule ends with a dot (.). Applications : I. expert systems II. specification language III. machine learning IV. robot planning V. automated reasoning VI. problem solving VII. intelligent data base retrieval VIII. natural language understanding
- 2. 1. Designa simple family relationship tree, assign necessary clause and rules to evaluate the following relationships: (a) Father (b) Mother
- 3. (c) Sister
- 4. (d) Brother

- 9. 4. Write a Prolog program to find the maximum between two numbers. We first check whether the numbers are equal or not. Then we check which number is larger i.e. the First one or the Second
- 10. 5. Write a Prolog program to concatenate two lists. Combining two list into one. 6. Write a Prolog program to delete an element from a list.
- 11. 7. Create Knowledge Base in Prolog for data given below: Person Name City Code Phone Number Kashif 02 544342 Asif 02 112345 Fahad 031 531612 Tareq 031 674245 Noman 081 753232 Aslam 081 812341 Jamil 02 912331 City Name City Code Dhaka 02 Cumilla 081 Chittagong 031 Find the solutions using the Knowledge Base: (a) What is the phone number of Kashif?
- 12. (b) Does Asif belong to Dhaka? (c) Where does Noman live? (d) Do Fahad and Tareq live in the same city? (e) Who lives in same city where Kashif lives?
