15:56 Changeset [10229] by sawinkle

#2109: Implemented a DepthFirstMapper, which works similarly to the DepthFirstMapper, but uses a queue to enable a breath-first tree creation.

12:34 Changeset [10228] by sawinkle

#2109: Updated DepthFirstMapper and abstract base class GenotypeToPhenotypeMapper:

  • Added new method SampleArity() to GenotypeToPhenotypeMapper to determine a random arity for a given node, depending on a maximum allowed arity.
  • Replaced the recursive depth-first mapping approach by a iterative one, which uses a stack of <node, arity> tuples. The recursive approach only generated trees with very small subtrees depending on the minimumArity of each node. Now, the iterative one uses the SampleArity() method and pushes/pops the <node, arity> tuples from/to the used stack. Therefore, it is not necessary to only allow the minimumArity, but also to deal with arbitrarily sampled arities per node.
