Literature Review Title: Statistical Model Checking : An Overview 
Chapter Title:  Black-box Systems: a note 
1. Abstract of Cited Paper (BIB001):  We introduce a framework for expressing correctness guarantees of model-checking algorithms. The framework allows us to qualitatively compare different solution techniques for probabilistic model checking, both techniques based on statistical sampling and numerical computation of probability estimates. We provide several new insights into the relative merits of the different approaches. In addition, we present a new statistical solution method that can bound the probability of error under any circumstances by sometimes reporting undecided results. Previous statistical solution methods could only bound the probability of error outside of an “indifference region.”

Literature Review:
Black-box Systems is an interesting class of stochastic systems whose treatment is beyond the scope of numerical techniques. Roughly speaking, a black-box systems is simply a system whose probability distribution (i.e., set of behaviors) is not totally known and cannot be observed. Hence, one can view a black-box system as a finite set of executions pre-computed and for which no information is available. In the context of such systems, Type errors and indifference region cannot play a role. Indeed, those parameters influence the number of simulations that can be computed, but here the simulations are given and you cannot compute more! A solution to this problem is to conduct a SSP test, without indifference region (i.e., δ set to 0) and assuming that the parameter n is fixed to the number of simulations that are given in advance. The difficulty is to chose the constant c in such a way that it becomes roughly equal to accept H 0 or H 1 if θ = p. In his thesis BIB001 and in BIB002 , Younes proposed a solution to the problem. He also shown that a previous solution proposed by Sen [25] is not correct. There are techniques to verify nested formulas over black-box systems. There exists no technique for the verification of unbounded properties. Hence there is still a lot of research to conduct in this area.
