Aminimum spanning treeis a spanning tree, such that the sum of all the weights of the edges is the smallest possible. Since it's a tree (and the edge weight sum should be minimal), there shouldn't be any cycles. Note:In case all edge weights in a graph are distinct, the minimum s...
Prim's Minimal Spanning Tree Algorithm Kruskal's Minimal Spanning Tree Algorithm Dijkstra's Minimal Spanning Tree Algorithm Divide and Conquer This class of algorithms involve dividing the given problem into smaller sub-problems and then solving each of the sub-problem independently. When the problem ...
building a minimal spanning tree computing a meta-clustering Self-Organizing Map SOM is a type of unsupervised Artificial Neural Network able to convert complex, nonlinear statistical relationships between high-dimensional data items into simple geometric relationships on a low-dimensional display. Introduct...
The minimum spanning tree (MST), a graph constructed from a distribution of points, draws lines between pairs of points so that all points are linked in a single skeletal structure that contains no loops and has minimal total edge length. The MST has been used in a broad range of scientifi...

Early versions of SciPy had minimal documentation, but this began to change with the 2006 release of aGuide to NumPy1. In 2007, Sphinx31made it possible to render hypertext and PDF documents automatically from plain text (docstrings) interspersed with Python code, and in 2008, pydocweb32enable...
