In this talk, I will explains the idea of tropical geometry and how it connect with counting of holomorphic objects. Via Floer theory, we will reduce open Gromov-Witten invariants on K3 surfaces to certain combinatoric, known as tropical discs. In particular, this will suggests an definition of refined open Gromov-Witten invariants.
