derivation of the fully connected layer Each node of the fully connected layer is connected to all nodes in the upper layer, which is used to synthesize the features extracted from the front. Because of its fully connected properties, the parameters of the general full connection layer are the most. forward calculatio

Note: This algorithm uses a directed graph as the input and provides a division of its vertex set based on the strongly connected component. Each node in graph only appears in a strongly connected component, even a single point. Start the deep-first search (if there are still unaccessed nodes after the DFS end, select one of them and then start from ). The accessed nodes are no longer accessed during the

number of integers in each row, indicates that line I allows the system to replicate and use the software of the system I. The end of each line is a 0, indicating the end of the bank's input. If a department does not allow any other department to use the system software, the bank has only one 0. Output For each set of test data, the minimum number of such allowable relationships that need to be added is output. Sample input

1093: [ZJOI2007] Maximum semi-connected sub-graph Time limit:30 Sec Memory limit:162 MBsubmit:3240 solved:1278[Submit] [Status] [Discuss] Description A g= (v,e) is called a semi-connected (semi-connected), if satisfied: U,v∈v, satisfies u→v or v→u, that is, for any two-point u,v in the graph, there is a forward path from U to V or a forward path from V to U. If g

Speaking ofAlgorithmWe often mention three of them, including the Tarjan Algorithm for strongly connected components described in this article. Professor Robert e Tarjan of Princeton University, who proposed this algorithm, was also the winner of the Turing Award in 1986 (For details, refer to the article titled "previous Turing Award winners ). First, clarify several concepts. Strongly Connected
