What do graph algorithms aim to solve?

Graph algorithms are specifically designed to address problems that involve graph data structures. These algorithms help in finding solutions for various scenarios, such as traversing a network, finding the shortest path between nodes, or determining the connectivity among different points in a graph. Graphs consist of vertices (also known as nodes) and edges that represent connections or relationships between these vertices.

The relevance of graph algorithms can be seen in numerous applications, including social network analysis, web page ranking using algorithms like PageRank, route optimization in mapping services, and network flow analysis in logistics. Their focused approach towards navigating and processing the relationships inherent within graph structures sets them apart from algorithms aimed at other areas like data encryption, database management, or user interface design, which are governed by different principles and concerns.
