By default, the algorithms are executed in the same order as corresponding algorithm elements have been added to the schema:

  1. The element with order 1 is executed.
  2. The element with order 2 is executed. It uses the results obtained from the step 1.
  3. And so on.

As each following algorithm element uses the results obtained from the previous element, setting the order can affect efficiency. For example, the less results are obtained on the first step, the faster the second algorithm is executed.

To change the order use the Set order submenu or Up / Down items in an algorithm element context menu.
