Hi everyone,
I’m looking for ways to practice graph modelling problems — the ones that don’t look like graph problems at first, but can be transformed into a graph and solved with graph algorithms.
Where can I find more problems like this on Codeforces (or other platforms)?
What’s a good method to get better at recognising “this can be modelled as a graph”?
Any recommended tags, problem lists, or practice strategies would be really helpful. Thank you!
