Algorithms are a series of steps that, when combined, form the basis of a computer program. A flowchart is a visual representation of the algorithm.

KS3 Introduction to programming Creating a program from an algorithm Programming is writing computer code to create a program, in order to solve a problem.

It covers basic algorithm design techniques such as divide and conquer, dynamic programming, and greedy algorithms. It concludes with a brief introduction to intractability (NP-completeness) .

Algorithms are turning up in the most unlikely places, promising to assert mathematical probability into corners of our lives where intuition, instinct and hunches have long held sway.
