There must be some meaning to the word "complete" its used every now and then.

Look at the diagram.

I tried reading previous posts about NP-

My question is what does the word "COMPLETE" mean?

Why is it there?

What is its significance?

N- Non-deterministic - makes sense'

P- Polynomial - makes sense

but the "COMPLETE" is still a mystery for me.
