+debugging notes: (high level )
+
+Gurobi cannot express < , >  (strickly less than or strickly greater than)
+
+
+Current problem:
+
+
+>> the teacher is not deterministic(i.e., gurobi) and requires further
+constraint to make it determinic. ---> maybe not sure sure? 
+
+
+a. currently gurobi doesn't minimize the objective function
+
+
+b. Understand winning tree
+
+c. understand what is the region represented by Dtree compared to shape produced by 
+sygus
+
+d.  Test this implementation on all the samples from this partion.
+(roughly 180 positive samples ) instead of just 20.
+
+
+e. how well does currently Dtree on 20 samples generalize to the  187  filtered samples
+and how well does it generalize to the entire region chosen?
+
+f. Chiao asks why did we succeedd on this one case?
+answer: we so good!
+
+For Angello specifically, go over chiaos's code to make sure we on 
+same page at the implementation level?

+
+Teacher starting at iteration 11 begins to return duplicate negative examples.
+
+    a. Tree is not correct
+    b. The fact that teacher can only express <= and not < is causing problem.
