Popis: For a position in the game of Hex, a fill pattern is a sub-position with one or more empty cells that can be filled without changing the position’s minimax value. A cell is prunable if it can be ignored when searching for a winning move. We introduce two new kinds of Hex fill – mutual and near-dead – and some resulting fill patterns; we show four new permanently-inferior fill patterns; and we present three new prune results, based on strong-reversing, reversing, and game-history respectively. Experiments show these results slightly reducing solving time on 8\(\,\times \,\)8 openings.
