In fact, the retrospective is very simple is the violence + judgment conditions, the conditions of the establishment of continued violence, conditions are not set to return to the next violence, the difficulty is to find the conditions for the establishment,In my opinion, backtracking is the pruning of violence, to find out the condition of the establishment of the basic solution ...Ideas:This question should find out the current bus order and the number of people can get on the train,, I used n

Tags: bzoj short circuit dynamic plan zjoi2006 spfa Some docks are composed of several edges. In some cases, some docks need to be repaired and cannot be used during this period. If you change the route, you will have to spend a certain amount of time to find the minimum cost within the specified number of days. Idea: Use spfa for short circuit. The key is dynamic planning. I thought about this rule for a long time and finally found myself thinking complicated. I first thought about how to use

DescriptionA has n cities in China, ranging from 1 to n. There are m two-way roads between cities. Each road imposes weight limitations on vehicles. Now there are Q trucks carrying goods. drivers want to know that each truck can carry a maximum of multiple goods without exceeding the vehicle weight limit. Input FormatThe first line has two integers n, m separated by a space, indicating N cities and M roads in.Next, line M contains three integers x, y, and z in each row. Each integer is separated

Ideas for solving problems: will be the shortest way of thinking change on the line. The Dis[i] Array records the smallest road capacity on the road from point 1 to I. Note Initialization of the DIS array. Personal experience: It was written because it was stuck in the initialization and tried several t

the Given an M-without-direction graph, you need to plan N-day transportation solutions. N days, every day from the S walk to T walk once, each point in some days can not pass. The cost is equal to the length of the path each day, and if the path chosen by the first day is different from the I-1 Day (i>1), it will take more than K to change the route price. Ask for the minimum total cost.(N Solving Brain hole problem, not too difficult. May at first

A strongly connected and directed simple graph. Each edge has two values, D and B. Set S to a non-null real subset of the point set. Q: Is there sum (d (I, j) No idea at all during the competition... The maximum stream is still a whiteboard. Idea:

This question is about selecting the maximum load path from 1 to n and finding the maximum load. To obtain the maximum load, we need to find the minimum load that each route can carry. You can use Dijkstra algorithm to find Assume that the current
