Order of the Golden Chain in New Jersey. Constituent Links began to form up and down the eastern coastline and continue to function in New Jersey, Pennsylvania and Rhode Island. It wasn't long after the Order of the Golden Chain was created that the country was in the thrust of the Great Depression. There was a strong need to belong to a fraternal organization such as the Golden Chain with members dedicated to helping others less fortunate than themselves. During that period, hundreds of thousands of dollars were spent by Constituent Links, from supplying food, coal and medical supplies to endowing much needed equipment for
Spanning tree and "routing loops", many routing protocols designed for such networks—including the Spanning Tree Protocol, Open Shortest Path First, Link-state routing protocol, Augmented tree-based routing, etc.—require each router to remember a spanning tree. A special kind of spanning tree, the Xuong tree, is used in topological graph theory to find graph embeddings with maximum genus. A Xuong tree is a spanning tree such that, in the remaining graph, the number of connected components with an odd number of edges is as small as possible. A Xuong tree and an associated maximum-genus embedding can be found in polynomial time. A tree is
