@cmuratori Is there a general-case name for flipping a problem around like this? I.e.: from "thing that can walk" to "region that is walkable". It is such a useful way of thinking.1 reply 0 retweets 0 likesShow this thread

Math-wise it's often called the "dual": https://en.wikipedia.org/wiki/Duality_(mathematics) … But that's mostly talking about things that mirror each other more literally, not necessarily in the abstract.
