Algorithms

Definition

An algorithm is the steps and rules that are followed when completing a process.
The main actions in an algorithm are sequence, selection and repetition.

Sequence

The sequence is the order of the steps.
- E.g. the toppings cannot be put on the cakes until they are cooked.

Selection

Selection is a yes/no choice.
A yes/no choice can be thought of as an ‘if ... then’ instruction.
E.g. should the cakes be taken out of the oven?
- If an inserted knife comes out clean, then yes.
- If an inserted knife comes out dirty, then no.

Repetition

Repetition means doing the same step over again.
