Stochasticity and Reproducibility in Terrestrial Planet Formation Simulations

Theory / Numerical Considerations:
- Divergence of nearby ICs in N-Body simulations: Planetesimal Disks.
- Why do they diverge?
- Can we estimate divergence rates?
- When do our estimates break down?
- Numerical issues and reproducability (different codes, truncation errors).

Impact on Planet Formation Simulations:
- Similar ICs will not reproduce the same system, need statistics.
- Present statistics for some demo cases.
- Can we match these to present observation?
- Can we use them to preduct future observations?
