ELI5: Explain Like I'm 5

Simplex tree

Well kiddo, imagine there's a big tree with lots of branches called a simplex tree. Each branch of the tree has a special code. Think of these codes like secret passwords for each branch. The tree helps sort things out and organize information according to these codes.

Now, let's say you have a bunch of things to sort out, like a bunch of toys in your toy box. You can use the simplex tree to quickly find the toys you want to play with. You start at the top of the tree and look for the branch with the right code. Then you follow that branch until you find the toy you want. It's like a treasure hunt for your toys!

The simplex tree is really good at organizing lots of things quickly because it splits up your choices into smaller and smaller groups. It's like playing "20 Questions" with your toys. Instead of asking "Is it a toy?" and "Is it red?", you'd ask "Does it have wheels?" and "Is it a toy car?".

Even grown-ups use simplex trees to organize things, like in computer programming or data analysis. But now you know the secret code to finding your toys faster!
