What are all types of variable expansions supported by Memgraph?
问题
我目前在我的学习项目中使用Memgraph作为图数据库。我了解到变量扩展在遍历图形时起着重要作用，特别是在查询节点之间的关系时。基于Memgraph的功能，有人能指定支持的变量扩展类型吗？
英文:
I am currently using Memgraph as a graph databases in my learining project. I understand that variable expansions play a significant role in traversing graphs, especially when querying relationships between nodes.
Based on the capabilities of Memgraph, could someone specify the types of variable expansions that are supported?

Memgraph支持以下类型的变量扩展：
-
深度优先搜索（DFS）： DFS是一种算法，它在回溯之前尽可能远地访问图中的每个分支上的顶点。
-
广度优先搜索（BFS）： BFS通过在移动到下一级的顶点之前访问当前级别的所有顶点来操作。Memgraph中的BFS是通过最短路径算法实现的：
-
SingleSourceShortestPath： 找到从单个源节点到图中所有其他节点的最短路径。
-
STShortestPath： 计算特定源节点和特定目标节点之间的最短路径。
-
-
WeightedShortestPath： 此算法在计算最短路径时考虑边缘权重。
-
AllShortestPath： 找到图中所有节点对之间的所有最短路径。
英文:
Memgraph supports following types of variable expansions:
-
Depth-first search (DFS): DFS is an algorithm that visits vertices in a graph as far as possible along each branch before backtracking.
-
Breadth-first search (BFS): BFS operates by visiting all the vertices of the current level before moving to vertices of the next level. BFS in Memgraph is implemented through shortest path algorithms:
-
SingleSourceShortestPath: Finds the shortest path from a single source node to all other nodes in the graph.
-
STShortestPath: Computes the shortest path between a specific source node and a specific target node.
-
-
WeightedShortestPath: This algorithm takes into account edge weights when calculating the shortest paths.
-
AllShortestPath: Finds all shortest paths between all pairs of nodes in a graph.
