Topkis's theorem

Topkis's theorem is like trying to solve a big jigsaw puzzle, but you only have a little bit of the picture to start with. Imagine you have a picture of a cute puppy, but it's been cut into jigsaw puzzle pieces and some pieces are missing.

Now you want to know where to find the missing pieces to complete the puzzle and see the whole cute puppy. Topkis's theorem helps you find the missing pieces by giving you a way to figure out which pieces are most important to find first, based on how they fit together with the pieces you already have.

So basically, Topkis's theorem is a way to find the missing pieces of a puzzle in the most efficient way possible, so you can see the whole picture.
