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 save the state of a simulation
  • The possibility to restore a simulation from this file.
  • The possibility to go backward to an older state of a simulation.

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;
}
}
}

Memorize simulation

model memorize

global {
init{
create people number:1;
}
}

species people skills: [moving] {

init{
location <- {50, 50};
}
reflex movement {
location <- {location.x + 1,location.y};
}

aspect base {
draw circle(5) color: color;
draw ""+cycle;
}
}

experiment memorizeExp type: memorize {

output {
display map {
species people aspect: base;
}
}
}
