Anylogic deterministic parameter variation
Best wishes for the new year. I have a question about the parameter variation. Using a python script I generate multiple solutions to be evaluated via simulation. The main variable is called individual and I would like the simulation to be performed for a specific range say 1-10 where I retrieve the simulation results for each value in this range. However, when I export the results to excel there exists some randomisation i.e. not all individual values are exported but for example individuals 0, 10, 5, 4, 1. I assume this is due to the seed value. Is there a seed value that can be used to simulate each individual value in a range following the normal order so 1,2,3 .... 10? Or is there another solution to achieve this?
Make sure you setup your ParamVar-experiment correctly. Independent of any random seed, replications, etc... If your setup looks as below, the ParamVar will run the model with all 10 values:
So it is either your setup that is wrong, or your outputs. I suggest you start with a simple trial without any Python parsing to see if normal setups work. Find the root cause (it is not the replications setting)
NOTE: If you run with "fixed seed", the model will be run 10 times with the same seed but a different value for myParam.
NOTE ALSO: The sequence of runs can appear random when you allow parallel evaluations: you cannot determine which is started first and which ends first. Switch off parallel evaluations and things are started and finished in sequence:
