 - etime < 600 : With the intended meaing that the end time for the node should be less then 600 seconds after the tree start time.
 
 The following constraints are automatically added for all nodes if times are used.
-- stime_lb < stime < stime_ub
-- etime_lb < etime < etime_ub
-- duration_lb < duration < duration_ub
+- stime_lb < stime_ub
+- etime_lb < etime_ub
+- duration_lb < duration_ub
 - stime_ub + duration_ub < etime_ub
 - stime_lb + duration_lb < etime_lb
 
 If the automatically generated constraints have a solution we can
 execute the tree.  We can also add additional constraints like:
-- etime < 600
-and check that we still have a solution.  It can slao be used to get a solution with
+- etime_ub < 600
+and check that we still have a solution.  It can also be used to get a solution with
 specific values for parameters that can then be added to the tree.
