Future Plan: add "hard deterministic mode"
toruseo opened this issue · 4 comments
In a local discussion with my colleague, it was suggested that a simulation mode that does not use any random element would be useful for some specific purposes such as numerical validation of theoretical models. Such mode can be implemented by adding alternative route choice and merging models. I will implement this in the future update.
Sounds useful! Are you planning on using random seeds, or another approach?
Doing deterministic (or reproducible) simulation by fixing seeds is already implemented, so this is something different.
For example in "hard deterministic mode", when merging, vehicles from a link with the largest merge_priority value will be always prioritized. Also, vehicles will always choose the shortest path. In the default mode, they are all stochastic (i.e., randomly chosen by weights) and not always convenient for analysis that need strict predictability.
Right, so basically removing all stochastic elements from the model.
