The Role of Algorithms

A set of steps to perform a task; further details in lecture 5
Examples illustrated are a washing machine and food

The Role of Algorithms (Continued)

Machine-like computer task execution requires algorithms
A representation of algorithms is a program
Computer programs work with the technology compatible with the machine
Program + Encoding + Loading into a machine = Programming
Program + Algorithm = Software
Contrasts with computer machinery components in its approach to task performance

The Origins of Algorithm

An object of study in mathematics
Earliest examples include Long Division, and Euclidean algorithms by ancient Greek mathematicians

The Euclidean Algorithm

Assumes two positive integers as input
A procedure for finding the greatest common divisor
Details regarding the procedure: Step 1. Assign M and N Step 2. Divide M by N Step 3. If the remainder R is 0, then N is the greatest common divisor otherwise continue

Machine Capability

Diagram illustrating a decision tree for machine requirement and algorithm definition and implementation determination

Computer Science Redefined

Definition of computer science
Computer science is more than just the computer and is also a study of problem-solving, and solutions
Computer science is concerned with the study of problem-solving and algorithms, as well as the study of problems which may not have solutions

Computer Science Redefined (Continued)

Computer science is a science of algorithms, with applications ranging from mathematics to engineering, psychology, biology and business administration
