We first want to analyze the networks path searching algorithms. Finding the shortest path between two nodes is a foundational concept for creating a distance metric which can then be used to conduct more advanced analysis. Examples of graphing nodes and edges can be mapping applications such as google maps, apple maps, waze, or uber, which are also natural applications for path searching algorithms.

Before exploring this idea, we introduce a few basic concepts about graphs. If two vertices in a graph are connected by an edge, we say the vertices are adjacent. If a vertex $v$ is an endpoint of edge $e$, we say they are incident. The set of vertices adjacent to $v$ is called the neighborhood of $v$, denoted $n(v)$.

The content is fine, but i found a lot of passages extremely talkative and pointless. For example, at the end of the euler's formula section, there is a 5 page section telling topology jokes, explaining what high school algebra is, mentioning roman numerals, and name dropping descartes. The book is about 250 pages long, but if you could remove all of the non-content, it would likely be about 80 pages.

Combinatorics is a branch of mathematics concerning the study of finite or countable discrete structures. Aspects of combinatorics include counting the structures of a given kind and size (enumerative combinatorics), deciding when certain criteria can be met, and constructing and analyzing objects meeting the criteria (as in combinatorial designs and matroid theory), finding largest, smallest, or optimal objects (extremal combinatorics.

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related. the objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called link or line).

Graph theory is concerned with various types of networks, or really models of networks called graphs. These are not the graphs of analytic geometry, but what are often described as \points connected by lines, for example: the preferred terminology is vertex for a point and edge for a line.
Now for a general graph, when you do have edges, we say that two nodes, call them xi and xj, are adjacent if they're connected by an edge, namely if xi xj is an edge. All right so for example, x5 is adjacent to x7, but it's not adjacent to x4, there's no edge there.
