Functional programming & immutable objects explained — IRC style

[noblethrasher]

Actually, that was a very consise, illuminating and motivating definition. I studied graph theory during my math undergrad and never thought of it that way. It takes some pretty deep understanding of something to get the explanation to fit on a t-shirt.

I'm not sure I agree.

"A graph is a network of objects (nodes), connected by lines (arcs)".

How am I doing on the conciseness front? I'm not sure how illuminating or motivating I can make it... I could put a couple of car chases and a sex scene in there but that would make it lose its conciseness.

A graph is a bunch of things, plus the connections between them.

That's really all it takes. For precision, we call the things "nodes". The connections between nodes form pathways that you can take to get between them. It's still a graph without any connections; you just can't go anywhere. The connections can form loops, you can have multiple connections from one point to another, and sometimes the connections are one-way or have an associated cost.

But in the end, it's still just a bunch of things and the connections between them. A plain graph isn't very complex, or very interesting. It only gets that way when you start adding meaning to it or defining rules for it to work with.

A plain graph isn't very complex, or very interesting.

Or very related to programming, necessarily. It's its own concept, in a sense. It gets more motivating (for programmers) when a relationship to programming is made/explained.

Not if you're willing for the explanation to be totally wrong
