Stationary --> relaxed

stationary --> relaxed

Comments: "stationary" means that the probability distribution does not shift any more.  However, as long as "innovation" is still switched in on MATSim (new routes, new times, ...), the result is not truly stationary.  Thus we avoid the word.  If innovation is switched off, the result is indeed a statinary process, but limited to the set of plans that every agent has at that point in time.

Possible future developments: not clear.  Minimally, publications should be precise.

Configuration:

<module name="strategy" >
	<!-- iteration after which module will be disabled.  most useful for ``innovative'' strategies (new routes, new times, ...) -->
	<param name="ModuleDisableAfterIteration_1" value="null" />
	<param name="ModuleDisableAfterIteration_2" value="950" />

	<!-- probability that a strategy is applied to a given person.  despite its name, this really is a ``weight'' -->
	<param name="ModuleProbability_1" value="0.9" />
	<param name="ModuleProbability_2" value="0.1" />

	<!-- name of strategy (if not full class name, resolved in StrategyManagerConfigLoader) -->
	<param name="Module_1" value="ChangeExpBeta" />
	<param name="Module_2" value="ReRoute" />

	<!-- maximum number of plans per agent.  ``0'' means ``infinity''.  Currently (2010), ``5'' is a good number -->
	<param name="maxAgentPlanMemorySize" value="4" />
</module>

 The above means:

• StrategyModule "ReRoute" (= innovative Module, produces plans with new routes) is switched off after iteration 950.
• StrategyModule "ChangeExpBeta" (= non-innovative Module, switches between existing plans) is never switched off.
• If an agent ever ends up with more than 4 plans, plans are deleted until she is back to 4 plans.  (Deletion goes via a "PlanSelectorForRemoval", which affects the choice set, and thus more thought needs to go into this.  Currently, the plan with the worst score is removed.)
