(2) Alice and Bob decide on a probability difference that they are willing to live with. For example, Alice might decide that she is not willing to be bound with a greater probability than 2 percent over Bob’s probability. Call Alice’s difference a; call Bob’s difference b. (3) Alice sends Bob a signed message with p = a. (4) Bob sends Alice a signed message with p = a + b. (5) Let p be the probability of the message Alice received in the previous step from Bob. Alice sends Bob a signed message with p´ = p + a or 1, whichever is smaller. (6) Let p be the probability of the message Bob received in the previous step from Alice. Bob sends Alice a signed message with p´ = p + b or 1, whichever is smaller. (7) Alice and Bob continue alternating steps (5) and (6) until both have received messages with p = 1 or until the date agreed to in step (1) has passed.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
