    My BF programs

    I found the following program:

    I found some improvements to Deedlit's original Ackermannian growth and expandal Turing Machines.

    Using this, I can prove that \(\Sigma(19) > f_{\omega+1}(163) > G\).

    Note: I found a machine that proves \[\Sigma(18) > f_{\omega+1}(7\cdot10^{57}) > G.\]


    Somehow states 3, 4 and 5 are completely obsolete in the original machine.

    In fact, removing them even increases the first string by three ones instead of two.

    You can simulate the machine on Anthony Morphett's site.


    This also works in the expandal growth machine, as that is just an extension o…

    The First International Googological Olympiad has ended. Here will follow the results, remarks and solutions. In the First International Googological Olympiad (FIGO for short) have participated four contestants, of which three have sent all problems to me. I consider the olympiad as a succes, given the fact that all contestants responded very positive. I've learned a lot of this olympiad as well (see the acknowledgements section), and I've enjoyed organizing it.


    Congratulations to all contestants. Fish is the winner of the contest.

    Googological Olympiad?

    January 25, 2015 by Wythagoras

    I was thinking about organizing a Googological Olympiad. I have already made a problem set. If there are at least 3 candidates, I will organize the olympiad, otherwise, I'll just post the problems. So:


    Also, if you want to practice:
