"Graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph."
A technique used to visit all nodes in a graph in a specific order, such as depth-first or breadth-first traversal. Graph traversal is useful for a variety of applications, such as finding the shortest path between two nodes.
Graph theory: The study of graphs, their properties and relationships, and how they can be used to model complex systems.
Graph representation: The various ways in which graphs can be represented, such as adjacency lists or matrices, and how to implement them in code.
Breadth-first search (BFS): A graph traversal algorithm used to explore all nodes in a graph that are at a certain level before moving on to the next level.
Depth-first search (DFS): A graph traversal algorithm used to explore the nodes in a graph by following a path as far as possible before backtracking to explore other paths.
Shortest path algorithms: Algorithms for finding the shortest path between two nodes in a graph, such as Dijkstra's algorithm or the Bellman-Ford algorithm.
Minimum spanning tree algorithms: Algorithms for finding the tree that connects all nodes in a graph with the minimum total weight, such as Prim's algorithm or Kruskal's algorithm.
Topological sorting: A method of arranging the nodes in a directed acyclic graph into a linear order such that for every directed edge from node A to node B, node A comes before node B.
Strongly connected components: A set of nodes in a directed graph where there is a path from every node in the set to every other node in the set.
Bi-partite graph: A graph whose nodes can be divided into two disjoint sets, such that every edge connects a node in one set to a node in the other set.
Travelling Salesman Problem: A classic optimization problem that involves finding the shortest possible route that visits a set of nodes (cities) and returns to the starting node (city).
Minimum Cut Problem: A classic optimization problem that involves finding the least-weighted cut in a graph, that is, the smallest set of edges that, if removed, would disconnect the graph.
Maximal matching in bipartite graphs: A matching in a bipartite graph is a set of edges that do not share any nodes. Maximal matching is the largest possible matching of edges, where no more edges can be added without violating the matching property.
Network Flow Algorithms: Algorithms that solves optimization problems on networks, such as the Max-Flow Min-Cut algorithm or the Ford-Fulkerson algorithm.
Backtracking algorithms: Search algorithms that try to systematically examine all possible solutions to a problem by generating all possible permutations or combinations of its elements, and rejecting those that fail to satisfy the problem's criteria.
Heuristic algorithms: Search algorithms that use approximations, rules-of-thumb, or domain-specific knowledge to guide their search, trading-off accuracy for speed.
Genetic Algorithm: A heuristic optimization algorithm that is inspired by the process of natural selection, and uses techniques such as mutation, crossover, and selection to evolve a solution over multiple iterations.
Ant Colony Optimization: A meta-heuristic optimization algorithm that is inspired by the behavior of ants searching for food, and uses pheromone deposit and evaporation to guide the search process.
Machine Learning algorithms: Machine learning algorithms can be used to predict relationships or classify elements in a graph. For example, clustering algorithms can be used to find communities in a graph.
Parallel algorithms: Algorithms can be designed to run concurrently on multiple processors or nodes in a cluster, making it possible to process large graphs faster. Techniques such as MapReduce can be used to split the graph into smaller subgraphs that can be processed in parallel.
Graph databases: Databases that are optimized for storing, querying and manipulating large graph datasets, such as Neo4j or Amazon Neptune.
Breadth-First Search (BFS): A graph traversal algorithm that traverses a graph level by level, exploring all the nodes at a particular level before moving on to the next level.
Depth-First Search (DFS): A graph traversal algorithm that traverses a graph by exploring as far as possible along each branch before backtracking.
Topological Sort: A graph traversal algorithm that orders the nodes in a graph such that for every directed edge (u, v), node u comes before node v in the ordering.
Dijkstra's Algorithm: A shortest path algorithm that finds the shortest path between two nodes in a weighted graph.
Bellman-Ford Algorithm: A shortest path algorithm that finds the shortest paths between all nodes in a weighted graph, even in the presence of negative edge weights.
A* Algorithm: A heuristic-based search algorithm that combines the best aspects of Dijkstra's Algorithm and Best-First Search to find the shortest path in a graph.
Kruskal's Algorithm: A minimum spanning tree algorithm that finds the minimum spanning tree of a graph by repeatedly adding the next cheapest edge that does not create a cycle.
Prim's Algorithm: A minimum spanning tree algorithm that finds the minimum spanning tree of a graph by starting from an arbitrary node and repeatedly adding the next cheapest edge that connects a previously visited node to an unvisited node.
Floyd-Warshall Algorithm: An all-pairs shortest path algorithm that finds the shortest paths between all pairs of nodes in a weighted graph.
Depth-Limited Search (DLS): A variant of DFS that limits the maximum depth of nodes to be explored, to avoid going too deep into the graph.
Bidirectional Search: A graph traversal algorithm that starts from both the source and destination nodes, and searches simultaneously until the two paths intersect, which is the shortest path.
Iterative Deepening Depth-First Search (IDDFS): A variant of DFS that repeatedly performs DFS with increasing depth limits, until the goal is found.
Strongly Connected Components (SCC): A graph traversal algorithm that finds all the strongly connected components in a directed graph, which are sets of nodes that can reach each other through directed paths.
Bridge-Finding Algorithm: A graph traversal algorithm that finds all the bridges (or cut edges) in an undirected graph, which are edges whose removal would cause the graph to become disconnected.
Articulation Point Finding Algorithm: A graph traversal algorithm that finds all the articulation points (or cut vertices) in an undirected graph, which are nodes whose removal would cause the graph to become disconnected.
