   * ***Computational Process***: take a computational standpoint to understand matters and processes, examine computational trade-offs, and project abstract computational processes to real-world phenomena.
   * ***Natural and Social Process***: draw inspiration from natural and social processes to uncover their computational nature, and disclose the underlying computational principles that govern complex systems.
   * ***Structure and Geometry***: study the structure, emergent behavior, patterns and geometry of the world.
-  * ***Sample, Optimization and Search***: explore the interconnected problems of sampling, optimization, and search, which are essentially about exploring vast search spaces efficiently but with different tools and perspectives.
