to implement Association Rules of the apriori algorithm, with detailed annotations The following section describes the program for finding k frequent item sets from two frequent item sets in the apriori algorithm. There are two problems in the program:1. It seems that the K of the while loop is always fixed, that is, the number of frequent two-item sets. Do you want to change the number of K after the first three frequent item sets? How can this problem be reflected?2. There are two for large l
fact, there are two other optional parameters. Attribute names in assigned are replaced by values, while attribute names in updated are merged by update, you can obtain the default values by viewing the source code of functools. For this decorator, it is equivalent to wrapper = functools. wraps (func) (wrapper ). 2.3.2. total_ordering (cls ): This decorator is useful in specific scenarios, but it is added after Python 2.7. It serves to add other comparison methods to the classes that implement

"URAL 1776" Anniversary Firework (probability DP) Main topic:N Rockets (3 The first idea completely deviated from ... Consider the interval DP: DP[I][J] Dp[i][j] represents the expectation of the waiting time of the rocket that ignites the i~j. But the expectation is to accumulate instead of taking the maximum value, so the interval DP is completely wrong ... (Though I'm not consciously feeling it right ....) The positive solution is to consider dp[i][j] for igniting a continuous I rocket, with
