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

For all paths from point 1 to N, the maximum size of the smallest capacity on the path.

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

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
