Lets say we have a set of coplanar regions defined in 2D space, and all regions form together one big region such that no hollow exists. In other words, a regions is subdivided into smaller ones by drawing random paths.
Is there an algorithm to re-identify/discover regions after reshaping one by either reshaping it's boundary without changing the topology or connectivity, or by removing a path forming a boundary of more than a region?
What's it called if any exist?
Is it an open research area?
What would be the right term to google it up?
Thanks.
