A **spanning tree** is a concept from graph theory and is particularly important in the field of computer science, networking, and related disciplines. Here’s a breakdown of the concept: 1. **Definition**: A spanning tree of a graph is a subgraph that includes all the vertices of the original graph and is connected, without any cycles. This means it is a tree structure that spans all the vertices in the graph.
Arboricity is a concept in graph theory that measures the minimum number of arborescent (tree-like) structures needed to cover a graph. Specifically, it indicates the minimum number of spanning trees required to represent the entire graph, ensuring that each edge in the graph is included in at least one of the trees. The arboricity of a graph can be determined by analyzing its structure; for instance, a graph that can be decomposed into a single tree has an arboricity of 1.
A Bridge Protocol Data Unit (BPDU) is a type of data packet that is used in the Spanning Tree Protocol (STP) and related protocols such as Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP). BPDUs are crucial for the operation of network bridges and switches in preventing loops in a Layer 2 network.
The Capacitated Minimum Spanning Tree (CMST) is a variation of the traditional Minimum Spanning Tree (MST) problem, which is a fundamental problem in graph theory and network design. In a typical MST problem, you aim to find a spanning tree of a weighted graph that connects all the vertices with the minimum possible total edge weight. However, the CMST introduces additional constraints related to capacity.
A degree-constrained spanning tree (DCST) is a specific type of spanning tree in a graph with the additional restriction that the degree (i.e., the number of edges connected) of each vertex must not exceed a specified limit. In other words, a DCST is a tree that spans all the vertices of a graph while ensuring that no vertex has a degree greater than a predefined upper bound.
The Euclidean Minimum Spanning Tree (EMST) is a specific type of minimum spanning tree where the vertices of the graph correspond to points in a Euclidean space, and the edges represent the straight-line (Euclidean) distances between these points.
The Expected Linear Time Minimum Spanning Tree (MST) algorithm is a type of randomized algorithm that constructs a minimum spanning tree for a given connected, weighted graph in expected linear time. The most notable of these algorithms is due to a technique based on random sampling or randomized method, which uses probability to improve the efficiency of MST construction.
Grid bracing is a structural engineering technique often used in the design and construction of buildings and other structures to provide lateral support and stability. This method involves the use of diagonal braces arranged in a grid pattern throughout a structure. The primary purpose of grid bracing is to resist lateral forces, such as those caused by wind or seismic activity, which can cause a building to sway or deform.
The K-minimum spanning tree (K-MST) problem is a generalization of the classic minimum spanning tree (MST) problem in graph theory. In the standard MST problem, the goal is to find a spanning tree of a weighted, undirected graph that connects all vertices with the minimum possible total edge weight. In the K-MST problem, the objective is to find **K distinct spanning trees** such that the sum of the weights of the edges in these trees is minimized.
The Kinetic Minimum Spanning Tree (KMST) is a concept derived from dynamic graph algorithms, specifically focusing on the minimum spanning tree (MST) in scenarios where the graph changes over time. In a typical minimum spanning tree problem, you have a weighted, undirected graph, and the goal is to find a tree that spans all vertices while minimizing the total edge weight. When the edges or weights of a graph change dynamically, maintaining an efficient representation of the minimum spanning tree becomes challenging.
The Markov Chain Tree Theorem is a result in probability theory that provides a method for calculating the probabilities of certain paths or transitions in a Markov chain by leveraging the structure of a tree. Specifically, it deals with the concept of expressing the stationary distribution of a Markov chain in terms of the transition probabilities and a tree structure, which can simplify computations and enhance understanding of the dynamics of the chain.
The Minimum-Cost Spanning Tree Game is a concept in cooperative game theory that represents a scenario where players (or agents) must cooperate to achieve a common goal, which is to construct a minimum-cost spanning tree from a given graph. In this game: 1. **Graph Structure**: You have a graph with vertices (nodes) and edges (connections) that have associated costs. The goal is to connect all vertices so that the total cost of the edges used is minimized.
A Minimum Degree Spanning Tree (MDST) is a variation of the Minimum Spanning Tree (MST) problem, which is typically concerned with connecting all vertices in a graph with the minimum possible total edge weight. In the context of an MDST, the objective shifts slightly. In an MDST, the goal is to find a spanning tree that not only minimizes the total edge weight but also limits the maximum degree of any vertex in the tree.
A Minimum Routing Cost Spanning Tree (MRST) is a type of spanning tree in a connected weighted graph that minimizes the total cost of routing, typically represented by the edge weights. In the context of networking or graph theory, this concept is particularly important when you want to ensure efficient communication or connectivity while minimizing costs associated with the connections between nodes.
A Minimum Spanning Tree (MST) is a subset of the edges of a weighted, undirected graph that connects all the vertices together without any cycles and with the minimal possible total edge weight. In other words, it is a tree that includes all the vertices of the graph, has the least total weight among all possible spanning trees, and contains no closed loops. ### Key Characteristics of a Minimum Spanning Tree: 1. **Connected**: An MST connects all vertices in the graph.
Minimum spanning tree-based segmentation is a technique used in image processing and computer vision to partition an image into distinct regions or segments by utilizing the properties of a minimum spanning tree (MST). The primary goal of segmentation is to simplify the representation of an image while preserving its important features, making tasks like object detection and recognition more efficient.
Multiple Spanning Tree Protocol (MSTP) is a network protocol used in Ethernet networks to prevent loops in network topologies while allowing for the efficient redundancy and load balancing of the network. Specifically, MSTP is an extension of the Spanning Tree Protocol (STP) and Multiple Spanning Tree Protocol (MSTP) to work across multiple VLANs (Virtual Local Area Networks).
In geometry, a net is a two-dimensional representation of a three-dimensional polyhedron. It is a flattened out version of the polyhedron that shows all of its faces connected in a single plane. By cutting along the edges of the polyhedron and laying it flat, the net reveals how the individual faces fit together to form the 3D shape.
Parallel algorithms for minimum spanning trees (MSTs) are algorithms designed to efficiently compute the minimum spanning tree of a graph by leveraging parallel processing. In a minimum spanning tree, a subset of the graph's edges connects all vertices with the minimum possible total edge weight and without forming cycles. ### Overview of Minimum Spanning Trees For a graph \( G = (V, E) \): - **Vertices (\( V \))**: The points in the graph.
A Rectilinear Minimum Spanning Tree (RMST) is a specific type of minimum spanning tree that is defined in a rectilinear (or grid-like) space, where the coordinates are aligned with the axes of a Cartesian plane. In a rectilinear geometry, the distance between two points is measured using the Manhattan distance (also known as the L1 distance), which is calculated as the sum of the absolute differences of their Cartesian coordinates.
Spanning Tree Protocol (STP) is a network protocol that is used to prevent loops in Ethernet networks. It was developed by Dr. Radia Perlman and is defined in the IEEE 802.1D standard. STP is essential in any network where multiple switches or bridges are used because Ethernet frames can circulate endlessly if there are loops, which can cause broadcast storms and degrade network performance.
A **tree spanner** is a concept in graph theory that involves spanning trees of a given graph. Specifically, a tree spanner of a connected graph \( G \) is a spanning tree \( T \) such that the distance between any two vertices in \( T \) is at most \( K \) times the distance between those vertices in \( G \). Here, \( K \) is a positive integer known as the stretch factor.
A Trémaux tree, named after the French mathematician Édouard Trémaux, is a structure used in graph theory, specifically in the context of exploring undirected graphs. It is used to represent the exploration of the graph and the paths taken during a traversal. Typically, a Trémaux tree is constructed during a depth-first search (DFS) or a breadth-first search (BFS) of a graph, where the edges represent the paths followed by the traversal.
The Xuong tree, known scientifically as *Baccaurea motleyana*, is a tropical fruit tree native to Southeast Asia. It is commonly found in countries like Malaysia, Indonesia, Thailand, and the Philippines. The tree belongs to the family Euphorbiaceae and is often referred to as "langsat" in some regions. The Xuong tree typically produces small, round or oval fruits that are yellowish or greenish when ripe and have a sweet, juicy flesh.
