We can do this by adding a boolean dirty flag to each node. If it’s set to true, then this is a node that needs to be recalculated. Otherwise, it’s up-to-date. Let’s start with these flags all set to false — we have an up-to-date tree. Now, when we update the input node, we can iterate over all the children of that node, and follow a simple algorithm:
A chess engine needs to make a move, search deeper, then unmake the move. In a normal language, local variables or a call stack handle this naturally. TeX has grouping-based scoping, but the engine’s design uses global state throughout (every \count register, every \newcount variable, every \newif flag is global).
