I'm currently preparing Combinatorics for IMO (International Mathematical Olympiad). I searched through the web (including some threads in MSE), for the best book recommendations. After a lot of "research", I decided to go with $$ Problem-Solving \ Methods \ in \ Combinatorics \ by \ Pablo \ Soberon. $$
Some other books I went through were either very difficult for me, or way too easy.
I started with the book, then I find it really difficult to understand the examples illustrated in it. It's not that I am a beginner in combinatorics, but I don't know why I was finding it very difficult.
I am just not able to get a proper book since a couple of days. And the only way for me to study is through a good book.
Can anyone suggest me the best books for combinatorics, highly relevant for Mathematical Olympiads? I will be very helpful.
I hope I have cleared things properly.
I know that a lot of people have asked the same question here already, but many of them were for Research related, and for just problem solving.
Thanks.
EDIT: AFTER A LOT OF CONSIDERATIONS, I HAVE DECIDED TO GO WITH THE BOOK $$ A \ Path \ to \ Combinatorics \ for \ Undergraduates \ $$ by $ Titu \ Andreescu. $
I just wanted to ask if this book is Olympiad oriented, or Olympiad relevant, as it's title doesn't seem to suggest that?
