Stabilization Methods for a Multiagent System with Complex Behaviours

Pseudocode 3

Hybrid model stabilization.

procedure HybridModelStabilization

input:  step: current simulation step, agents: the list of agents; maxDifference: a threshold for social model outcome difference;

   minStepsToChange: the minimum number of simulation steps between changes; eps: a very small number;

   lastChange: a list with the last simulation step when a change was made to the internal model of an agent;

   noChanges: the number of changes made to the system so far

output: updated noChanges

begin

   for each agent in agents do

    difference = modelDifference(, step) − modelDifference(, step − 1)

     if difference < maxDifference and  step − lastChange() > minStepsToChange then

      a.SocialModels(a.FirstChoice).Outcome = a.SocialModels(a.SecondChoice).Outcome − eps

      lastChange() = step

      noChanges = noChanges + 1

     end if

   end for

   return  noChanges
