    06-Assignment Tehtävä

    Saatavilla vasta, kun: You are a(n) Opiskelija

    This exercise is aimed at giving an opportunity to practice the concept of uniformity and non-uniformity as well as the equivalence of the hardness of search problems and decision problems in the worst-case.

    EDIT 4.3.2019 16:08 (clarification):

    The 'advice' (a_n) that is mentioned in the exercise is a bitstring that should depend on the length of the input but not on the contents of the input.

    EDIT 9.3.2019: fix typo in the assignment title (3 and 4 ==> 6) and update correct dl to the pdf too

    Exercises to practice statistical distance and the notion of a distributionally one-way function.
