Tropical geometry famously provides a way in which to count solutions to enumerative (or curve counting) problems in algebraic geometry. In order to achieve this, each tropical curve is counted with a certain multiplicity. Ideally, one would like this multiplicity to be localized over “smaller” problems attached to the vertices. I will give an introduction to these ideas, explain some subtleties that make it fun to think about, discuss what implications this has for older questions in the subject.
