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 : " + save_simulation('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;
}
}
