WebNov 13, 2009 · In this paper, we propose a puzzle solving algorithm to treat these problems. Based on the fact that most of nonograms are compact and contiguous, some logical rules are deduced to paint some cells. Then, we use the chronological backtracking algorithm to solve those undetermined cells and logical rules to improve the search efficiently. WebJun 26, 2024 · 2. To address the inefficacy of phase saving for decisions following a chronological backtracking, we introduce a new metric, decaying polarity score (DPS), and DPS-based phase selection heuristic. DPS seeks to capture the trend of polarities assigned to variables with higher priority given to recent assignments. early end of life tool
