The Descent Editing

The Descent Editing. By Kristina Olubaite. From the beginning of the car scene shots are short and long, they are not happening very quickly. Everything looks to happen very naturally. You are not expecting anything dangerous to happen as the family is travelling together in the car.

Descent Search Depth

Descent Search Depth. After 30,000 generations, cases 7 and 8 have not converged to maximum d h solution. Case 9 converges to it, but only after 17,746 generations. Conclusion: The optional descent search is needed. L could be small (e.g. like L=2) but convergence will be slowed. Adaptive L.
