 Programme 1)      Pull all layers from each sequentially the stacks of boxes (bottom-up) to find whether these layer exceed certain min and max threshold ( stack boxed hit) .   other than this if  the sequential layered stacks that has some dummy variable such sum greater  example is start  -/layer:  [2, 3,4,-1][-6,5,8][-4, 3 ] -   will result in  
 boxes Sum -(sum of weight of the dum var value so in this case (boxes sum   is   one ) listing first the boxes that has Sum 0 than  (that have permananat hits but some links that cause an error will detect with error) raise warning  

Do you think this is the first task enough or do I need to provide one more task?[/INST]
