1. Using templates may cause code bloatUsing templates is a great way to save time and avoid code reuse. You do not need to enter 20 identical class names manually, each class has 15 member functions, instead, you just need to enter a class template and have the compiler instantiate 20 specific classes and 300 functions you need. (The member functions of a class template are implicitly instantiated only if they are used, so 300 member functions are generated only if 300 functions are actually us

In order to improve development efficiency, help developers to work on the same project process to streamline the development process to achieve the goals of the team, there are many collaboration tools in the market, such as Slack,trello,asana,jira.3.

Of course, we can do a topological sort before executing the algorithm to determine if there is a negative power loop.We use the array dis to record the shortest path estimate for each node, we can use adjacency matrix or adjacency table to store graph G, we recommend using adjacency table.SPFA algorithm Idea (Dynamic approximation method):set up a FIFO queue q to hold the nodes to be optimized, optimize each time you remove the first node of the team, and use the current shortest p

You may not know who created these, but it is the moments of pleasure that accumulate to allow you to open these interesting applications. 　What is micro-interaction So what is micro-interaction? We can define this: micro-interaction is a single task-based interaction with a digital device. It's

the event node graph (event-node graph), each event corresponds to an action and all the actions associated with it are completed.So now we need to find out the earliest time to finish the event, just find the longest path from the first event to the last one. It is often meaningless to have the longest path problem with a positive loop (Positive-cost cycle). Because the event node diagram is a no-ring diagram, then there is no need to worry about the circuit, so that there is no scruples.The f

updates, if the n-1 after relaxation can also update the shortest distance, then there is a negative weight in the diagram of the loop (take a triangle of the negative weight of the loop, the picture can be understood). The algorithm flow of the Bellman-ford algorithm is as follows: (1) Initialization: The distance array dis is initialized to the source point of the weight value (can also be initialized to +∞), and then updated to the source point dis is 0; (2) Relaxation of the update operatio

to vertex 3rd. DIS[2]+E[2][3] Dis[2] represents the distance from vertex 1th to 2nd, e[2][3] means 2->3 this edge. So dis[2]+e[2][3] means that from point 1th to Vertex 2nd, and then through 2->3 this edge, to reach the 3rd vertex of the road. We found dis[3]=12,dis[2]+e[2][3]=1+9=10,dis[3]>dis[2]+e[2][3], so dis[3] to be updated to 10. This process has a technical term called "slack". That is, the distance from vertex 1th to point 3rd is dis[3], th

Poj 3565 Ants KM Question: Give the coordinates of n ant and n class apple trees. To let each ant go to an apple tree, the route cannot be repeated. a feasible solution is proposed. Analysis: When the distance and the smallest value of a matching feasible ant are obtained, the KM algorithm can be directly used to find the matching of the minimum weight of a bipartite graph. Another approach is to assume a match first, and adjust it if there is a cross. Code: //poj 3565//sep9#include #incl
