• O(N)变成了O(logN)？我今天碰到一个同样的问题，不过是别人问的 (无内容) - Nixrreg (0 bytes) 2011-02-24, 00:22:12 (551876)
  • the goal is always constant latency, logN is the second best. (无内容) - steven (0 bytes) 2011-02-24, 01:40:41 (551902)
    • how can you measure latency with big O notation in an concurrent environment? (无内容) - ak70 (0 bytes) 2011-02-24, 02:10:43 (551904)
      • why not? (无内容) - steven (0 bytes) 2011-02-24, 02:26:17 (551906)
        • because of the concurrency issues. Unless the algorithm - ak70 (255 bytes) 2011-02-24, 02:33:08 (551909)
          • big O works for concurrent also, - steven (109 bytes) 2011-02-24, 02:50:15 (551913)
            • what about the delays caused by resource locking? - ak70 (139 bytes) 2011-02-24, 03:19:35 (551915)
              • The delay for syncrhonizing tasks is no different than any other delay. - steven (34 bytes) 2011-02-24, 10:32:40 (552047)
  • 减低latency又不是算法优化，用不着O之类的东西。 (无内容) - ak70 (0 bytes) 2011-02-24, 00:43:59 (551888)
