NTrees

Declaration:	TRndForest.NTrees: integer;
The property NTrees controls the number of trees used within a random forest. A meaningful number of trees is typically between 50 and 100. The valid range of NTrees is from 1 to 500, setting NTrees to values below or above the valid range will automatically restrict it to the valid range.

Hint:

You can find the optimum number of trees by scanning the allowed range in the Random Forest Development Tool.
