replay several times the same simulation setup

[lyuba mancheva]

Hello everybody,

For my simulation I need to compare 2 different strategies for one type of agents
and I need that the rest of the simulation setup is the same for avoiding any other bias.
I need to reload and replay the same simulation setup ( e. g. the location of different agents in the beginning of the simulation, their attribute values).
Is there a easy way to save the initial state of the simulation and then reload it for the next simulations?


Thank you very much,
Best

Hi

You can read in the manual about creating multiple simulations. Basically, you create a new simulation in the experiment block and this new simulation can have different parameter values (indicating different strategies) that you want to explore.

Hello,
I have found in Gama examples the model called CreateSimuGraph2 in Create Simulation from File.gaml which resolves my question.
Here is the snippet :

reflex store when: cycle = 5 {
write "================ START SAVE + self " + " - " + cycle ;
save saved_simulation_file('saveSimu.gsim', [simulation]);
write "================ END SAVE + self " + " - " + cycle ;
}


and then :

....

action _init_ {
create simulation from: saved_simulation_file("saveSimu.gsim");
}

....
