Okay, little buddy, let me try to explain it to you in a way you can understand. So, have you ever played a game where you make a puzzle but then you can take it apart and put it back together again? That's kind of what a reversible reference system propagation algorithm does.
In computer programming, we use something called a reference system to keep track of things. Think of it like a map that shows you where everything is. But sometimes we want to change things around or move things to a different spot on the map. That's where the reversible part comes in – it means we can trace our steps back and undo any changes we've made.
The propagation part of the algorithm is like spreading out the map to see where all the different pieces are. It helps us make sure we're not missing anything when we make changes.
So, in short, a reversible reference system propagation algorithm helps us keep track of stuff in a computer program and makes it easy to change things without losing track of where everything is. Just like how you can take apart a puzzle and put it back together again!
