Hello there,
As some might know, I am a double ICPC World Finalist and Computer Scientist. I compiled a collection of graph theory problems to help you become more proficient in Bipartite Graphs, Functional Graphs, and Eulerian Paths.
This is a comprehensive list of 15 problems of medium to hard difficulty, with all the reasoning and formal proofs needed to solve them. It goes deeper than the usual experience of solving problems in competitive programming, where the formal aspect is usually overlooked.
The problems are taken from:
Codeforces
AtCoder
Andrew Stankevich Contests
ICPC World Finals
This book is for you if you are up for a challenge and willing to allocate time to solving these 15 problems. The ideas exposed here are not only challenging but also some of the most beautiful ones I was exposed to during my competitive programming years.
This book is also for you if you are a complete beginner in graph theory. It contains an introductory section with all the basic knowledge needed to understand the presented problems.
Also, the book is not free. This is why:
It takes time and effort to create a product with this depth.
You will use the book best if you have already paid. I've seen this often where people don't do what they should because they don't have something to hold them accountable. If you are willing to pay money, you will be willing to learn from the book.
By purchasing this product, you will gain access to the current draft and receive all future updates for free, ensuring that you stay ahead of the curve.

Unfortunately, this is not always the case. Seeing something out comes from determination, not from money paid. There are definitely many people out there who just pour money on things but don't put any effort into anything.
In spite of this small inaccuracy, your post has earned an updoot from me.
