Simulation Observer - adolgert/CTDE.jl GitHub Wiki

Every time the simulation determines a next time and transition, it calls an observer and calls it with this signature.

StateObserver(state::Array{Int,1}, affected_keys, clock_name, time::Float64)

• state is the state of the system.
• affected_keys are those substates which were affected when the last transition fired.
• clock_name is the name given to that transition.
• time is the time at which that transition happened.
• Returns: The observer returns a boolean indicating whether the simulation may continue.

In practice, this function is a closure which adds data to a list of data, or writes that list to disk.
