Hardware design cost savings experience notes1, these pull the high pull low resistance with the big resistance relationship is not small, choose an integer 5K barThere is no 5K resistance on the market, the closest is 4.99K (accuracy 1%), followed by 5.1K (accuracy 5%), its cost is 20% higher than the accuracy of 4.7K 4 times times and twice times. 20% the resistance value of the precision is only 1, 1.5,

Solution report Question: There are n stores, M providers, and a matrix of K commodities Ideas: The question of creating a graph cannot directly build all the information into a graph, because N and M have a relationship with K. If we build a graph like that, we need to split K into M classes, the K type that each warehouse connects to the warehouse, and then connects to N at a cost, But this is actually not the case. We will find that the relations

Idea: This question mainly refers to the creation of graphs for a long time. It was not judged to be full before, so I read this knowledge point again, then we found that there was a bug when the maximum flow of our minimum fee was full, and it was changed. Figure: start to see the question to know that this question is the largest flow of the minimum cost, and then do it without looking at the explanation. Then I couldn't find the answer to my self-b

within the organization, and the organizational costs will continue to rise. In addition, from the perspective of Chinese folk culture, if you want to make people loyal, you have to pay a lot.

The proliferation of virtual servers eliminates the cost-saving benefits that many IT organizations crave when applying server virtualization, said an IT professional who led the company's virtualization initiative. Boeing computing infrastructure designer Jett Thompson says we are under great pressure to find ways to save money as much as possible. Virtualization has been one of the hottest topics since virtualization has found many of the benefits

Color a TreeTime limit:1000ms Memory limit:30000kTotal submissions:7144 accepted:2458DescriptionBob is very interested in the data structure of a tree. A tree is a directed graph in which a special node was singled out, called the "root" of the tree, and there is a unique PA Th from the root to all of the other nodes.BOB intends to color all the nodes of a tree with a pen. A Tree has N nodes, these nodes is numbered 1, 2, ..., N. Suppose coloring a node takes 1 unit of time, and after Finishi ng

Item M24: Understanding the cost of virtual functions, multiple inheritance, virtual inheritance, and RttiC + + compilers must implement every feature of the language. The details of these implementations are, of course, determined by the compiler, and different compilers have different ways of implementing language features. In most cases, you don't have to worry about these things. However, the implementation of some features has a great impact on t
