3.2A Characteristics of an Algorithm Notes
An algorithm is a step-by-stepprocedure for solving a problem or performing a task.
Algorithms are everywhere in our daily lives:
Cooking recipes are algorithms for making a dish.
Navigation apps use algorithms to find the fastest route.
Social media platforms use algorithms to show content.
Algorithms are based on a linear set of instructions that lead to the solving of a problem.
Note
Algorithms are not just for computers. They can be used in any situation where a problem needs solving or a task needs completing.
Characteristics of an algorithm
Unambiguous
An algorithm must be clear and precise. There should be no room for interpretation.
The algorithm must be direct and explicit and not up to perspective.
Finite
An algorithm must have a specific finite number of steps that lead to the relevant output.
Example
A recipe with infinite steps would never finish cooking the dish.
