    The Surprising Result

    -

    - Intuitively, you might expect the number 6 (opposite to 12) to be the most likely to be painted last, - since it's the farthest from the starting point. However, the probability is exactly 1/{numPositions - 1} for - every number from 1 to {numPositions - 1}! This is because once all but one number is painted, the random walk - will eventually reach that last number, regardless of where it is. -

    Credits & History

    +

    + This puzzle is based on the Erdős Discrepancy Problem, posed by Paul Erdős in the 1930s + (with a $500 prize!). The "Prisoner's Walk" framing comes from various mathematical expositions, + popularized by James Grime's singingbanana video. +

    +

    + 2014: Boris Konev & Alexei Lisitsa proved C=2 has maximum length 1,160 using SAT solvers + (generating a 13GB proof!). 2015: Terence Tao proved that NO infinite sequence + can have bounded discrepancy, settling the problem completely. +

    Eternal Domination on a Grid

    -

    - Explore the m-eternal domination problem on a 12×10 grid. Guards must maintain - a dominating set while defending against arbitrary attack sequences. -

    -
    - - - - - - Mathematical Background - -

    - Dominating Set: A subset S of vertices in a graph G such that - every vertex not in S has a neighbor in S. Think of guards placed at certain - vertices that can "watch" their neighbors. -

    -

    - m-Eternal Domination: A two-player game where the defender - places guards on vertices, and the attacker repeatedly attacks unguarded vertices. - The defender responds by moving guards (all can move simultaneously, but only to - adjacent vertices) such that one guard ends on the attacked vertex and the guards - still form a dominating set. -

    -

    - The Challenge: The defender wins if they can maintain a dominating - set forever against any attack sequence. The m-eternal domination number γ∞(G) is - the minimum number of guards needed to win. -

    -     -     - - - Defense Strategy - -

    - This implementation uses the strategy from research on finite grids: -

    -
      -
    • Border guards: All vertices on the border (rows 0, 1, 8, 9 and - columns 0, 11) are always guarded, forming a protective cycle C.
      • -
    • Interior guards: Placed in a pattern that ensures every interior - vertex is dominated by exactly one guard.
      • -
    • Defense mechanism: When attacked, interior guards shift toward - the attack, potentially pushing a guard to the border. Border guards shift along - "complementary paths" to fill the resulting gaps.
      • -
    -     -     - - - Reference - -

    - Based on: "m-Eternal Domination and Variants on Some Classes of Finite and - Infinite Graphs" by Calamoneri et al. (CIAC 2025), which establishes bounds - and strategies for eternal domination on various grid types including square, - hexagonal, and triangular grids. -
