	summary
		Algorithm engineering views design, analysis, implementation, and experimental analysis of algorithms as an integrated process in the tradition of Popper's scientific method.
		Several aspects of algorithms for miminum spanning trees most of which are related to data structures.
		Our algorithm can be viewed as a positive answer to this question albeit using a different (better) algorithm.

	Take a BrainSip
		'''Kruskal's algorithm''' is an algorithm in graph theory that finds a minimum spanning tree for a connected weighted graph.
		Kruskal's algorithm is an example of a greedy algorithm.
		With the use of a suitable data structure, Kruskal's algorithm can be shown to run in O (m log n) time, where m is the number of edges in the graph and n the number of vertices.

	Minimum Spanning Tree
		Algorithm 479 [Pag74] and Algorithm 613 [HJS84] of the Collected Algorithms of the ACM are Fortran codes for minimum spanning tree, the former in an implementation of a point clustering algorithm.
		Interestingly, it is Boruvka's algorithm that serves as the foundation to the new randomized one.
		Algorithms for generating spanning trees in order from minimum to maximum weight are presented in [Gab77].

	Greedy algorithm Summary
		But a greedy algorithm is not an algorithm proper--it is a heuristic, it works in stages, making a series of short-term decisions that will be the best possible at the present time, without regard for what might happen in the future.
		Even when a greedy algorithm fails to provide the best solution to a problem, it usually provides a good estimate of what the actual solution is. Such is the case with the traveling salesman problem, in which a salesman tries to visit a certain number of cities without repetition while traveling the least possible distance.
		Examples of such greedy algorithms are Kruskal's algorithm, Dijkstra's algorithms for finding Single-Source Shortest paths and Prim's algorithm for finding minimum spanning trees and the algorithm for finding optimum Huffman trees.

	Undirected Graphs and Minimum Spanning Trees
		Prim's algorithm is very similar to Dijkstra's single-source shortest path algorithm and indeed the given version of the former was created by simple edits to the latter.
		Kruskal's algorithm certainly leads to a spanning tree T but it is necessary to prove that T is minimal.
		On the other hand, the edges in the tree produced by Kruskal's algorithm are sorted by their weight, because it considers short edges first.

	CSCI 3300 programming assignment 3
		For this problem, the algorithm is sufficiently difficult that it is a good idea to think about the algorithm before proceeding with the design.
		Kruskal's algorithm adds the edges starting with the cheapest ones, and, since it is supposed to find a cheapest possible spanning tree, it seems to be doing something right.
		Obviously, if Kruskal's algorithm fails to work, then somebody should be able to come up with both G and T, where T is the correct minimal spanning tree, and where Kruskal's algorithm gets the wrong answer.

	AMPL Example
		The file kruskal.txt is an AMPL implementation of Kruskal's algorithm for the Minimum Spanning Tree (MST) problem.
		In fact, it's possible to implement Kruskal's algorithm so that it requires on the order of (m log n) operations.
		By way of contrast, there is no known algorithm for TSP where the maximum number of basic operations is bounded above a polynomial function of the number of vertices and edges in the graph.

	greedy algorithm (Site not responding. Last check: )
		Note: Prim-Jarnik algorithm and Kruskal's algorithm are greedy algorithms that find the globally optimal solution, a minimum spanning tree.
		In contrast, any known greedy algorithm to find a Hamiltonian cycle might not find the shortest path, that is, a solution to the traveling salesman problem.
		If there is no greedy algorithm that always finds the optimal solution for a problem, one may have to search (exponentially) many possible solutions to find the optimum.

	The Minimum Spanning Tree Problem
		This is basically a program that solves a well-known minimum spanning tree problem by using a slightly changed Kruskal's algorithm.
		For example, this can be accomplished with two passes through the list of edges: on the first pass edges are placed into k distinct "buckets" according to their weights, and on the second pass the contents of the buckets are combined back into a large list.
		n) can be attained on the remaining part of the algorithm by using a simple labeling scheme in which groups of vertices are formed by combining trees, the root of which serves as the unique label for the group.

	Graphs and Trees (Shortest Distance,Searching Algorithms, and Minimum Spanning) by Jonathan Stewart
		The two methods of finding this optimal network are via Prim's algorithm and Kruskal's algorithm.
		Kruskal's algorithm works by ordering the edge distance from least to greatest and then making the connections:
		First we begin at A. A is not J, so we move on to examine nodes B, C, and D. None of these are equal to J,so we continue the process until we find J. As we continue, we look at nodes E, F, G and continue the same process.

		This process is continued until all nodes, N, are connected by N-1 edges, of minimal weight.
		Kruskals algorithm is essentially the same thing, except it starts by making a priority queue out of all of the edges.
		Dijkstra's Shortest Path Algorithm is very similar to Prims Algorithm, with one major exception, it keeps track of the cumulative distance from the root to every node, rather than the distance of just each edge.

		Then complement the graph with all other possible direct connections between edges and give those vertices a large length/weight (larger than the number of edges shoudl be enough).
		- the algorithm is meant to be recursive, the change to currentPath is not meant to affect further iterations of the loop started in 3.
		So an algorithm that is very slow/consumes much space whatever is not a problem i guess.
