Abstract: Systems and methods for pre-computing and memoizing simulations are disclosed. In an embodiment, a computer system may retrieve processing filters for running a simulation. The computer system may generate a simulation query based on the simulation filters and hash the simulation query. The computer system may determine whether a simulation result corresponding to the hashed simulation query has been pre-computed and stored.
