kruskal s algorithm in c

someone asked, why is F (x-1) +1 and 1 compared AH. The reason is simple: take F (2) as an example, F (2) =f (1+1), and f (1) = 1, that is, the result of F (2) is associated with F (1), whereas F (2) itself has an initial value of 1, the final value of F (2) According to the question is supposed to be through F (1) The value of the operation and its initial value select the larger one. And so on in the back. 2, this method is very ingenious, the main idea is this, I don't care what your sequen

The Kruskal algorithm (Kruskal's algorithm) is one of the simpler understandings of the two classical minimum spanning tree algorithms. This fully embodies the essence of the greedy algorithm. The approximate process can be represented by a graph. The choice of the map here borrows from Wikipedia. Very clear and intuitive.First step, we have a graph with several

This is a creation in Article, where the information may have evolved or changed. Common internal sorting algorithms are: Insert sort, hill sort, select sort, bubble sort, merge sort, quick sort, heap sort, cardinality sort, etc. Summarize with a picture: Merge sort (English: merge sort, or mergesort) is an efficient sorting algorithm that creates an O (n log n) on a merge operation. It was first presented by John von Neumann in 1945. The

A history of particle swarm optimization Particle swarm optimization (Complex Adaptive system,cas) is derived from the complex adaptive system. CAS theory was formally introduced in 1994, and CAS members are called principals. For example, the study of bird systems, in which each bird is called the subject. The subject is adaptable, it can communicate with the environment and other subjects, and change its structure and behavior according to the process of communication "learning" or "accumulati

Data Structure and algorithm simulation algorithm C ++ implementation, data structure and algorithm AlgorithmSimulation Algorithm: simulates the entire process. By changing the parameters of the model in mathematics, you can observe the changes in the process state caused by these parameters.Algorithm concept: use rand

than 100, so the corresponding questions are generated directly. The following class implements efficiency considerations in two scenarios. If traversal is fast, you can directly call AddTest to add one more time. If the query is fast, you can use KindOfTestNeed to extract the query conditions, the results generated by the current code are the same each time. If there is a real library, you can use the Randomization of the query results and the Randomization of the KindOfTestNeed condition to g
