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

] and e.weight () If the value is not less than distto[w] it is said to be invalid and ignored, and if it is small, the data is updated. The slack operation is shown in the following code:Private void Relax (Directededge e) { int v=e.from (); int w=e.to (); if (distto[w]>distto[v]+e.weight ()) { distto[w]=distto[v]+e.weight (); EDGETO[W]=e; } }Vertex relaxation: For a vertex, relaxing it means rel

A muddle of work has been going on for almost two years.Over the past two years, I've found that I've been piling up code and reaping little.

The image is divided into two layers:

The pattern has array mode and dictionary mode. The general situation uses the array mode, which sometimes falls down.

After three years of work, I found that my energy will decrease with many things. Things that I felt very passionate and interesting may gradually become "irrelevant. I don't know whether this is a kind of free and easy, or a kind of slack. In short, I will try my best to overcome the present situation and make full use of my spare time. In addition, I recently got a "quasi-expert badge". To be worthy of this badge and to get rid of the previous
