Recall that an opaque predicate is a conditional that is actually not a conditional. That is, the conditional always evaluates to the same result, although it is not obvious.

(a) Why is an opaque predicate a useful defense against reverse engineering attacks?

(b) Can Collatz conjecture be used to construct opaque predicts? Why or why not.

(c) Suppose someone tries to use a statistic model/machine learning model/deep learning model to construct opaque predicts. What would be the advantage of such a design? What would be the general concern for such a model-based obfuscation? Or you think thats not even feasible? Explain your answer.
