Implement the Age-Layered Population Structure![1].

-*Abstract:** To reduce the problem of premature convergence we define a new method for measuring an individual’s age and propose the Age-Layered Population Structure (ALPS). This new measure of age measures how long the genetic material has been evolving in the population: offspring start with an age of 1 plus the age of their oldest parent instead of starting with an age of 0 as with traditional measures of age. ALPS differs from a typical evolutionary algorithm (EA) by segregating individuals into different age-layers by their age and by regularly introducing new, randomly generated individuals in the youngest layer. The introduction of randomly generated individuals at regular intervals results in an EA that is never completely converged and is always exploring new parts of the fitness landscape. By using age to restrict competition and breeding, younger individuals are able to develop without being dominated by older ones. Analysis of the search behavior of ALPS finds that the offspring of individuals that are randomly generated mid-way through a run are able to move the population out of mediocre localoptima to better parts of the fitness landscape. In comparison against a traditional EA, a multi-start EA and two other EAs with diversity maintenance schemes we find that ALPS produces significantly better designs with a higher reliability than the other EAs.

2015-02-18 15:39:36: @NimZwei commented

r12035

  • Added LayerUniformSubScopesProcessor which introduces an intermediate ExecutionContext which translates array-based parameters to single-value parameters.
  • Updated ALPS-OperatorGraph to make usage of the new LayerUniformSubScopesProcessor.
  • Added a temporary operator for calculating number of selected sub scopes because presetting the value during operator parameterization does not work for the new intermediate context. Note: the change of the PopulationSizeParameter still causes an error when creating a new layer. This will be fixed soon.

r12036

2015-02-19 12:52:52: @NimZwei commented

r12039 Per-layer parameter can be used to define all multiple layers. If less values are specified in the array the last value is used for all subsequent layers. I.e. when the array has the length 1, all layers use that same one value. From a usability point of view, this behavior may has to be discussed more in detail.
