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.

1. Where can I find more problems like this on Codeforces (or other platforms)?

2. 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!
