Proof of fixed-point theorem

Daniel Duffy

C++ author, trainer
here's another great tip for Quasar and everyone

The source of all great mathematics is the special case, the concrete example. It is frequent in mathematics that every instance of a concept of seemingly great generality is in essence the same as a small and concrete special case.

Paul Halmos


Get it working, then
Get it right, then (and only then)
Get it optimised

It's a mindset; trying to get the most general result in one iteration NEVER works.
