This is not the second edition of the book Counting. Instead, it contains topics which are built upon the contents discussed in the first book. Generally speaking, this book targets AIME, national and international level competitions. Some techniques are quite advanced.Techniques discussed in this book include bijection, recursion, counting integer solutions (balls-in-boxes), combinatorial identity, binomial/multinomial expansion, generating functions etc. Some examples and practice problems are at national and international math competition levels.For more information about this book, please visit

Focusing on innovative tiling techniques beyond traditional methods, this book introduces a unified tiling representation framework to study three unique approaches utilizing irregular tile shapes. These techniques aim to improve performance by minimizing communication latency, balancing workloads, and enhancing parallelism. The insights provided could significantly benefit researchers in the fields of compilers and high-performance computing, offering fresh perspectives on optimization strategies.
