There are 3 standard algorithms to solve the minimum-spanning-tree problem, one of which was used in reconstructing evolutionary tree. The discovery of the close proximity analysis leads to the development of a method for studying the evolution of trade networks. It was also used to model the ...
The advantage of the zipper forest is that it allows the graph/tree to be navigated in an iterative manner. Potential uses of such a forest can be to represent a minimum spanning tree, a DOM document, an undo tree, etc. Adding, replacing and deleting items is done in amortized constant ...
Identifying Different Meanings of a Chinese Morpheme through Semantic Pattern Matching in Augmented Minimum Spanning Trees Galmar and Chen (2010) introduced the first corpus-based computational approach to the problem of identifying the different meanings of a polysemous Chines...

The constrained forest problem seeks a minimum-weight spanning forest in an undirected edge-weighted graph such that each tree spans at least a specified number of vertices. We present a greedy heuristic for this NP-hard problem, whose solutions are at least as good as, and often better than...
quarantined for a minimum of fourteen days while authorities examine options and begin to sort out how to re-open the country to travellers from disease free nations. There will be many more details to iron out, some anticipated and others wholly unanticipated. It’s the nature of the beast....
He was happy, though, as he was keeping himself alive with the bare minimum. As the Light of the rising sun would come up, he would dress up with the few pieces of clothing he had, put his shoes and walk fast to the nearest village 2 km from his ”home”. There, he would ...
selling wood from trees that have been removed for heating requires careful planning and consideration. It is essential to ensure that the wood comes from legal, sustainable sources, is cut to the correct size and is appropriately seasoned, to ensure maximum heat output and minimum environmental im...
“This work shows that the geochemical signature associated with thecoolingevent is not unique but occurred four times between 9,000 and 15,000 years ago,” said Alan Brandon, Ph.D., professor of geosciences at University of Houston. “Thus, the trigger for this cooling event didn’t come...
