1. Preparation:(1) Prior probability: Based on past experience and analysis of the probability, that is, the usual probability, in the full probability of the expression is "from the result of the fruit"(2) Posterior probability: refers to the probability of re-correcting after obtaining the "result" information, usually the conditional probability (but not all of the conditional probability is the posterior probability), in the Bayesian formula as a result of the "fruit seeking cause"For exampl

follows: List list = new Linklist (); // create a linked List List = Test1Dao. listC1 (); // Circular linked list While (list. size> 0 ){ String c1 = list. remove (0 ); // Search If (Test11Dao. find (c1 )){ // Found. The condition is not met } Else { // Tell the client that no result is found. If yes, the result is returned. } } In this way, each record in the list will request the test11 block, but its mechanism is to find a row that is returned, so each time it may scan 1 ~ 34 to generate the

DataSet ObjectThe DataSet object is another component that is specifically designed for data access to a data source, so he can use it for multiple different data sources. A DataSet object contains a collection of one or more DataTable objects that have

BZOJ3504[CQOI2014] Dangerous BridgeTest instructionsThere are N islands, some of which are connected by bridges, and the roads on the bridge are two-way, but only one person can pass at a time. Some of these bridges are dangerous bridges. Alice wants to travel between the islands Al and A2 (from Al to A2 and from A2 to Al for a round trip). At the same time, Bob wants to travel between the island BL and B2 to bn times. In this process, all dangerous b

.S (n + 1, K) = S (n, k-1) + NS (n, k ). The second type of Stirling is the number of methods that divide a set containing n elements into k non-empty subsets. Recursive Formula,S (n, n) = S (n, 1) = 1,S (n, k) = S (n-1, k-1) + KS (n-1, K ).Put N balls with Different balls into k unlabeled boxes (n> = k> = 1, and the box cannot be blank. (that is, the number of cases where a set containing n elements is divided into k sets) Recurrence formula: S (n, k) = 0 (k> N) S (n, 1) = 1 (k = 1)
