Resetting a for loop counter and restarting the computation

Question

I have a while loop nested inside a for loop to do a calculation of a model. 
Lets say I am on the for loop counter 4. Suppose I wanted to keep track of the number of iterations on one the while loop, and if it exceeded a certain number say 100, exit the while loop.  I am doing this to avoid my model calculation being stuck at a spot due to optimization issues. I now want to restart the calculations of for loop counter 4. 
Is there a way to do this in labview?

Well first of all, if you are going to restart the loop with the same program inside it after it got stuck is it not just going to get stuck again creating a permanent loop in the code? Would you not just want to move on and have some sort of identifier that one of the for-loops got stuck?
But I would recommend simply nesting your while-loop inside of another while loop, then connect the exit for the out while-loop to some variable from the inner while-loop, so if the optimization did not occur properly then it simply repeats the inner while-loop.
Although I stick by my thoughts that you will just end up in a permanent loop if the optimization fails the first time.
