    • Property Summary changed from Add support for the absolute value function abs(x) for symbolic regression problems to Add support for abs(x), AQ(x) and CubeRoot(x) for symbolic regression problems

  • Ticket #2915 – Description

    initial v7  
    1 We do not yet support abs(x). It should be straight forward to add this.
     1It would be nice to add support for the functions abs(x), AQ(x) (analytical quotient) and CubeRoot(x).
     2
     3We already support a general root function. However, this is implemented as power(x, 1/round(x)) which makes it hard to use it in combination with constants optimization.
     4
     5We also provide a separate symbol for the squared root. For some problems a cube root might also be necessary.
