  The log operator with the operator for the algorithm selected and value set to Execution-Time. 

   

  You can do this from either the CrossValidation or from the Algorithm itself, but I would recommend putting it inside your X-Validation so you can take a count of every execution of the chosen algorithm and can later calculate average run-times.

   

  Sample process:

   

  <?xml version="1.0" encoding="UTF-8"?><process version="7.3.000">
    <context>
      <input/>
      <output/>
      <macros/>
    </context>
