- - ### Method Detail

    - #### solutionUpdated

          void solutionUpdated(Solution<V,T> solution)

      Called by the solution when it is updated, see `Solution.update(double)`.
      Parameters:
        `solution` - source solution

    - #### getInfo

          void getInfo(Solution<V,T> solution,
                       Map<String,String> info)

      Called by the solution when it is asked to produce info table, see `Solution.getInfo()`. A listener can also add some its info into this table.
