What's the config input to not mutate endTime at all? (MutateActivityTimeAllocation)

[fastGeorge]

For my purposes, I don't want the endTimes or durations of activities in the simulations to be changed in MutateActivityTimeAllocation. In an attempt to achieve this, I set the mutationRange to 0 (config.timeAllocationMutator().setMutationRange(0)). However, this causes an issue in the method mutateTime. When mutationRange is set to 0, mutationRangeBins is also set to 0 which causes an error in this.random.nextInt(mutationRangeBins) since it expects input > 0. Is this the desired behaviour and should I disable endTime mutations in some other way? Thanks in advance!

private double mutateTime(final double time, double mutationRange) {
double t = time;
int mutationRangeBins = (int) Math.ceil( mutationRange/mutationRangeStep);
t = t - mutationRange + (2*this.random.nextInt(mutationRangeBins)*mutationRangeStep) ;
if (t < 0) {
t = 0;
}
// note that this also affects duration
return t;
}

I think that the way to go would be to not use time mutation at all as a strategy. Something like not have a config section such as

		<parameterset type="strategysettings" >
			<param name="disableAfterIteration" value="-1" />
			<param name="executionPath" value="null" />
			<param name="strategyName" value="**TimeAllocationMutator**" />
			<param name="subpopulation" value="null" />
			<param name="weight" value="0.1" />
		</parameterset>

Or set its weight to 0.

That seems to have done the trick! Thank you :)
