My main question is how do you stop a schedule.scheduleRepeating()?? or 
is there something better to use for what i want to do??

I am new to MASON and agent based programming in general, so I am sorry 
if this is a basic problem but I have spent about 12 hours almost 
straight on this now and have not got anywhere :-(

What I want to do is run a simulation until a flag = true store that 
result and then run the same simulation again (x number of times). 
Preferably with the results at the end of each simulation being 
displayed in a chart. (simulations could run one after another or all 
together should not matter that much, would maybe like to have an option 
for either though if one is not a lot more complex than the other.

The problem I am getting at the moment is stopping the 
schedule.scheduleRepeating() I just cant do it! think i have tried 
everything but it does not seem to stop.

I have included part of my code so you can see what I am trying to do 

/*** MODEL CLASS ***/

 public void start()
            grid = new IntGrid2D(N, N);
            grid = new IntGrid2D(gridWidth, gridHeight);
         NKSpace_Gen nkGen = new NKSpace_Gen(System.currentTimeMillis());

*// ** I basically want to get this **bit below **to repeat x number of 
time and then get it to stop when the agent flags a variable in the 
agents step method to be true ***

         Agent agent1 = new Agent(System.currentTimeMillis());


/*** AGENT CLASS ***/

    public void step(SimState state)
        if (mutantNeighbours.numObjs > 0 && higherFitness == false)
            if (higherFitness == true)
                higherFitness = false;
            System.out.println(" Higher Fitness Values Found ");
            System.out.println("Fitness Value: "+ localPeak);
            peakFound = true;            *//** this is where I set 
peakFound to true and where I want to store the localPeak value and stop 
that agent at present it just keeps printing the two system.out.println 
to the console forever. (note they are only there for debug I actually 
will have a graphics showing the values. *
        if (peakFound == false)
        System.out.println("*** Current Fitness Searched ***");
        System.out.println("Fitness Value: "+ currentFitness);

ANY HELP or comments would be MUCH APPRECIATED!!

Many Thanks
