Overview
The integrator determines how differential equations are stepped forward in time. TVBO supports deterministic and stochastic integration schemes.
Available Integrators
| Integrator | Order | Stochastic | Use Case |
|---|---|---|---|
| Euler | 1 | No | Fast, simple |
| Heun | 2 | No | Better accuracy |
| EulerMaruyama | 1 | Yes | Additive noise |
| HeunStochastic | 2 | Yes | Multiplicative noise |
YAML Specification
integration:
integrator:
name: Heun
dt: 0.1
duration: 1000Choosing an Integrator
- Deterministic simulations: Use
Heunfor a good accuracy/speed trade-off - Stochastic simulations: Use
HeunStochasticfor multiplicative noise,EulerMaruyamafor additive noise - Step size (
dt): Smaller is more accurate but slower
