Save and Restore simulations

Last version of GAMA has introduced new features to save the state of a simulation at a given simulation cycle. This has two main applications:

  • The possibility to step forward and backward in a simulation,
  • The possibility to save the state of a simulation in a file and to restore a simulation from this file.

Save a simulation

experiment saveSimu type: gui {

reflex store when: cycle = 5 {
write "================ START SAVE + self " + " - " + cycle ;
write "Save of simulation : " + saveSimulation('saveSimu.gsim');
write "================ END SAVE + self " + " - " + cycle ;
}

output {
display main_display {
species road aspect: geom;
species people aspect: base;
}
}
}

Restore a simulation

experiment reloadSavedSimuOnly type: gui {

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

output {
display main_display {
species road aspect: geom;
species people aspect: base;
}
}
}

Saved simulation file type: gsim
