I'm taking a class in enumerative combinatorics. The professor focusses on the complexity of solving combinatorics problems like partitions etc. I'm using Enumerative Combinatorics but it does not talk about complexity. What's a good book/website/resource that touches on enumerative (or even extremal) combinatorics and complexity of counting?
What's a good advanced textbook/resource for studying the complexity of counting and combinatorics?
