Webprecondition for instance, the input xto a program P(x) may follow a Laplacian distribution. The correctness property of interest is a probabilistic postcondition, which we de ne as an expression over probabilities of program outcomes. For instance, we might be interested in ensuring that P(r>0) >0:9 the program In computer programming, a postcondition is a condition or predicate that must always be true just after the execution of some section of code or after an operation in a formal specification. Postconditions are sometimes tested using assertions within the code itself. Often, postconditions are simply included in the documentation of the affected section of code.
