      Constraint Framework: Add Initial Prototype · cbbb38d5
      Alexander Diewald authored 
      
* Deprecates the IConstraintEncoding.
* The "framework" holds the initial or generated constraints (by
  decoders) and allows to query them for the construction or their
  modification.
* Constraints are associated with Genotype instances to restrict the
  modifications applied to them.
* Constraints are associated with Phenotype types such that constraints
  can be declared before the instance are constructed in order to make
  the construction operations aware of the constraints to be applied.

      Parameters: Improved defaults. · e9c52c60
      Alexander Diewald authored 
      
* The previous parameter set caused the optimizer to spend half of the
  iterations for random generation, not the search itself. Now, only the
  first 5 iterations are spent on the creation of the initial pool.
* Adjust the default of the parallel execution to "true".

      Operators: Compare Operators by their type. · 4f59c39f
      Alexander Diewald authored 
      
* An injection exception occurred when launching the MOEA DSE a second
  time from the same AF3 instance. Here, operator modules that maintain
  an internal map keep the entries of the previous run (which are
  replaced). This triggered an equals check of operator keys when the
  operators for the next execution should be placed in the internal
  operator selector maps. Within the equals check, one operator (from
  the prev. execution) had an instance of the operator such that the
  comparision would be based on the operator instances. Thus, an
  operator would be instantiated by the given injector during the
  binding phase causing the Exception.
* In order to obtain a correct operator representation in the internal
  maps an to resolve the above problem, base the Operator Key hash and
  equals method on the OperatorTypes only. We only allow one operator
  type per genotype anyways such that the new equals operation correctly
  implements the concept and "old" operator instances are cleaned out.

      Multithreading: Thread-safe for large models. · 06475537
      Alexander Diewald authored 
      
* Use scope enter and exit calls to clean cached objects in thread-
  specific caches such as the PhenotypeCache that is used to collect the
  results of the decoders in  a single top-most decode() call.
* Add the @ThreadedMethod annotation to trigger the Treaded scope entry
  and exit calls for cache handling. It denotes that the code within
  such an annotated method places objects the cache that need to be
  removed after exiting the method. An method interceptor is used for
  this purpose.
* Pass Injectors to demanding classes such as the GuiceDecoder by the
  Provides mechanisms.
* Extend the usage of the injector to generate objects (not DSE-process
  specific objects).

      DI: Add missing bits for parallel DSE processing. · f51fb646
      Alexander Diewald authored 
      
* Modify the Dependency Visitor such that it can also evaluate the
  providers of artifacts instead of the artifacts alone.
* Install only those Decoders and Creators in the DSE Process that are
  actually needed to produce the result types.
* Correct the ThreadScope implementation.
* Add a thread-local cache for the parallelized decode phase that
  collects the created Phenotypes.
* Modify the cache mechanism for the create phase similar to the
  thread-local cache of the decode phase.
* Change the register mechanism of CreatorModules and OperatorModules
  such that they can be associated with their corresponding Genotype
  more easily.
* CreatorModules used in the DSE process are now created by Guice to
  allow method interception (evil bug fixed).
