Changed
- DeterministicEpiModel is now MatrixEpiModel
- SymbolicEpiModel is now SymbolicMatrixEpiModel
- in StochasticEpiModel and during visualization, a more efficient mechanism checks for whether the simulation has ended for good
Added
- Added models that are based entirely on events. In this way, we can easily implement time-dependent rates and have single models that can do everything at once: symbolic evaluations, numerical evaluations, and stochastic mean-field simulations
- time-dependent rates are integrated using a time-varying Gillespie algorithm
- EpiModel, StochasticSIModel, StochasticSIRModel, StochasticSISModel, SymbolicEpiModel (based on events rather than rates)
