What's an algorithm?

The parent comment raises a valid distinction.

> In contrast, a heuristic is an approach to solving problems without well-defined correct or optimal results.[2] For example, although social media recommender systems are commonly called "algorithms", they actually rely on heuristics as there is no truly "correct" recommendation.

What are the consequences of conflating the two terms? I’m not sure yet.

Not really, as described in the quote you shared, it is common to refer to "recommendation systems" as "algorithms", even if its not actually such a thing.

There are plenty of examples of well-known aliases to concepts that obfuscate actual meaning in the English language, but they aren't wrong, as language is usage.

It’s actually not such a thing. So is the distinction valid or not?

It depends how pedantic you’re feeling.

What’s a word, if you really think about it?
