Finding dense spanning trees (DST) in unweighted graphs is a variation of the well studied minimum spanning tree problem (MST). We utilize established mathematical properties of extremal structures with the minimum sum of distances between vertices to formulate some general conditions on the sum of ...

A Minimum Spanning Tree (MST) is a subset of the spanning tree of a connected and weighted graph whose sum of weight of edges is minimum in comparison to all possible spanning trees of that graph. In other words, it’s the smallest possible tree that connects all the vertices that have ...

Finding dense and sparse spanning trees reduces to a discrete optimization problem. The provided source code employs genetic algorithm which is one of the well-known metaheuristics methods to find DST and SST approximately. 点赞(0) 踩踩(0) 反馈 所需:1 积分 电信网络下载 ...
This problem can be modeled as a Steiner tree problem (STP) in graphs. Although these problems all involve finding spanning trees in graphs, they have different constraints and objective functions, requiring heuristic algorithms tailored to their specific problem characteristics, without a uniform ...

When the O(n2) time complexity of exact kNN graph generation is infeasible due to the size of the data set, efficiently generated approximate kNN graphs can be used. Many of the efficient approximate kNN graph generation procedures are based on spatial trees since the cost of their construction...
