Graph Description Languages (GDLs) are specialized languages used to specify, represent, and manipulate graphs or graph-like structures. These languages provide a way to express the nodes, edges, properties, and relationships of graphs in a formal manner, making it easier for software tools and algorithms to process and analyze graph data. **Key Features of Graph Description Languages:** 1.
Category theory is a branch of mathematics that focuses on the abstract study of mathematical structures and relationships between them. It provides a unifying framework to understand various mathematical concepts across different fields by focusing on the relationships (morphisms) between objects rather than the objects themselves. Here are some key concepts in category theory: 1. **Categories**: A category consists of objects and morphisms (arrows) that map between these objects. Each morphism has a source object and a target object.
