Question:There are N cities, and then the adjacent matrix between these cities is directly given. In the matrix,-1 indicates that the two cities are not connected by road, and other values represent the path length.If a car passes through a city, you must pay a certain amount of money (possibly a toll ).Now, from City a to City B, the cost is the sum of the path length, plus the total toll of all cities except the start and end.Calculate the minimum
The layer-3 switch technology is quite common, So I studied how to save the company's cost by using the layer-3 switch technology. I would like to share it with you here, hoping it will be useful to you. The layer-3 Switch Technology Access solution helps reduce the networking cost for networks with large scale and many downstream nodes. At present, more and more companies need to establish their own enterp
In the previous article (http://www.cnblogs.com/ms0017/archive/2011/07/26/2117676.html), we listed the large-scale Web sites developed at home and abroad using ASP. The last mentioned use. NET development of large-scale Web sites and Lamp/java platforms for cost comparisons. In fact, in many cases, fees are not necessarily higher than the cost of free. Because the development of a site to use which platform
Main TopicThere are n vertices on a graph, numbered from 1 to N, there are some non-forward edges between vertices, edges have length, require to go from vertex 1 to vertex N, and then from Vertex n back to Vertex 1, where it is not necessary to go through each vertex, but the edge of the path required to walk only once. Find the minimum length of the path from 1--->n-->1.Problem AnalysisEach non-forward edge can only walk at most once, which could be considered as a capacity of only 1 of these

Minimum cost tree (0404) Problem descriptionThe following method is called the minimum cost of the letter tree: Given a sequence of positive integers, for example: 4,1,2,3, adding them without changing the position of the number, and using parentheses to mark the sum of each addition.For example: ((4+1) + (2+3)) = ((5) + (5)) = 10. Except the original number is not 4,1,2,3, the rest are intermediate results
Title Link: BZOJ-1221Problem analysisAlgorithm one: Minimum cost maximum flowFirst, this is a classic network flow problem. Create two nodes per day, one I means using towels, and one I ' means the towel used this day.Then I to T even Ai (the number of towels needed for the first day). From S to I ' Even AI, so the new used towel this day is AI.Then I ' can be connected to (i+1) ', said to stay until the next day to deal with, I can also flow to i+p+1

At first glance, we built a bipartite graph. However, we found that there was a lower bound and no upper bound minimum cost flow problem... Problem conversion: the so-called difficult is opposite! At present, a row/column must have at least K rows and at least the sum. Isn't that row/column having at most K rows and column having the maximum sum? In fact, that is, a maximum of K is used to convert the maximum

Cross entropy cost function 1. Cross-entropy theory
Cross entropy is relative to entropy, as covariance and variance.
Entropy examines the expectation of a single information (distribution):
H (p) =−∑I=1NP (xi) Logp (xi)
Cross-Entropy examines the expectations of two of information (distributions):H (P,Q) =−∑I=1NP (xi) logq (xi)For details, please see Wiki Cross entropy
