Flow chart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≥ A yields "yes" (or true) (more accurately the number b in location B is greater than or equal to the number a in location A) THEN, the algorithm specifies B ← B − A (meaning the number b − a replaces the old b). Similarly, IF A > B, THEN A ← A − B. The process terminates when (the contents of) B is 0, yielding the g.c.d. in A.

In mathematics and Computer science, an algorithm is a self-contained step-by-step set of operations to be performed.

Cory Doctorow on Rob Smith's Rage Inside the Machine:

Smith shows how the parts of machine learning that do work refute some of the uglier philosophical ideas that have risen in currency as algorithms have taken over our society -- just as the Victorians had their "blind watchmaker," the rise of evolutionary algorithms has given a new lease on life to eugenic theories about survival of the fittest and the need to purify and protect the "best" among us.
