Useful for problems like TSP, optimal assignment, and subset-based counting where n is small (≤ ~20) and the order/combination of included elements matters. Covers core bit tricks (set/check/clear bit, iterate submasks) along with example problems.\n\n### Issue details\n\nBitmask DP represents a subset of elements as bits in an integer, where bit i being 1 means element i is included. The DP state dp[mask] (or dp[mask][i]) stores the best result for that subset, and transitions move from one mask to another by adding an element via mask | (1 \u003c\u003c i). It's used when problems involve small sets (n ≤ ~20) and require tracking exactly which elements have been chosen, e.g., TSP, optimal assignment, and subset partitioning.\n\n### Additional Information\n\n_No response_","author":{"url":"https://github.com/priyanka-hotkar","@type":"Person","name":"priyanka-hotkar"},"datePublished":"2026-06-30T07:09:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/7503/Java/issues/7503"}
