LISP

Invented by John McCarthy (1958)
Two simple data structure (atoms and lists)
Heavy use of recursion
Interpretive language
Variations
- Scheme
- Common Lisp (de facto industrial standard)
Most widely used AI programming language
Functional Programming Paradigm
Low maintenance overhead

Atoms may be;
- Numbers : (real 1.0, integer 1)
- Symbols : a consecutive sequence of characters (no space) e.g. a, x, price-of-beef
- Two special symbols: T and NIL for logical true and false
- Strings : a sequence of characters bounded by double quotes e.g. "this is red"

Valid Objects

Its also a list
Uses prefix notation:

(function-name arg1,arg2 ... argN)

It returns function value for the given list of arguments
Functions are either provided by LISP function library or defined by the user

Function Calls

Examples:

(+ 1 3 5) 9

(/ 3 5) 3/

(/ 3.0 5)

(sqrt 4) 2

Function Calls

Command Line Prompt
