Path-constrained rendezvous

Imagine you and your friend are playing tag in a really big park. You both start off in different parts of the park and you want to meet up at a specific tree in the middle of the park.

But, there are lots of trees and bushes in the way that you have to go around and it might take you a long time to get to the tree.

Path-constrained rendezvous is like a game where you and your friend are trying to meet up at the specific tree, but you have to follow certain paths to get there. These paths might be like specific roads or trails that you have to walk along.

You both have to follow the same paths to get to the tree. It's kind of like a treasure hunt where you have to follow clues to find the treasure.

The goal is for you and your friend to meet up at the specific tree using the same paths, even though you might be starting from different places.

This kind of game is important because it can be used for things like robots or drones who need to meet up at a certain location while following specific paths. It's a way for them to communicate and work together to achieve their goal.
