Issue migrated from trac ticket # 2472

milestone: HeuristicLab 3.3.13 | component: Problems.GeneticProgramming | priority: medium | resolution: done

2015-08-27 07:01:05: @gkronber created the issue

This plugin should hold GP problems such as the aritificial ant or the lawn mower problem.

This ticket replaces individual tickets #2421, #2422, and #2469

For integration into stable merge the following changesets:

I left the SymbolicExpressionTreeProblem in the encoding plugin because I believe it fits better there (as a potential base class for all problems using the symbolic expression tree encoding). It is not strictly necessary to include a reference to Problems.GeneticProgramming.

  • r13055: changed ordering of symbols in the grammar for the artificial ant problem to make sure the new problem produces the same results as the old implementation
  • r13056: changed GP artificial ant sample to use new implementation
HeuristicLab-Trac-Bot commented 8 years ago

2015-10-22 20:57:48: @gkronber commented

r13057: changed lawn mower sample to use the new implementation and added assertions for the results of the unit test (let's see if they work on the builder...)

2015-11-15 15:39:16: @gkronber commented

r13163 (sorry this commit messages incorrectly references #2069, but it was not possible to edit the svn log message afterwards)

  • adapted the multiplexer sample to use the specific implementation of the multiplexer problem instead of symbolic regression.
  • Added best known solutions for the Boolean benchmark problems

all changesets mentioned in the comments are relevant but probably it is best to review the code in

  • HeuristicLab.Problems.GeneticProgramming and
  • HeuristicLab.Problems.GeneticProgramming.Views
HeuristicLab-Trac-Bot commented 8 years ago

2015-11-18 17:05:29: @mkommend commented

Reviewed the SymbolicExpressionTreeProblem and HL.Problems.GP and the according views and unit test for sample creation.

Comments:

  • Odd source code organization (cloning and persistence in a region at the EOF)
  • BasicSymbolicRegression
    • Recreates constants every time the problem is changed => not reproducible
    • Couldn't the solution be transformed to a standard data analysis tree (simplify, optimize?
  • Why are the boolean problems restricted (number of bits) and why is this done in the evaluation function?

Overall pretty cool and easy to implement problems. I am especially impressed on how easy tree evaluation can be performed for the boolean and regression problems.
