I am currently engaged in the study of graph theory for my master's thesis. For my work, I need to use the functions is_isomorphic and is_subgraph. I want to gain a deeper understanding of the underlying code for these two functions.
However, when I attempt to access the documentation using the search_src() function, I receive the following warning message: "Warning: the Sage documentation is not available".
Could you kindly guide me to where I can find the source code of these functions?
I appreciate your assistance in advance.
Best regards.
