When you create a new scenario in STEM, you need to specify which solver to use. A solver is simply the method used to determine how the state of a simulation changes from one time step to the next. Models for populations and diseases in STEM are all designed to carry out this change or "delta" calculation given a current state. How the delta value is applied to determine the next state is where solvers differ.
