 Circle packing in a circle

Circle packing in a circle refers to the arrangement of smaller circles within a larger circle in such a way that the smaller circles do not overlap and are as densely packed as possible. This problem can be seen as a geometric optimization problem where the objective is to maximize the number of smaller circles that can fit within the confines of the larger circle while adhering to certain rules of arrangement. ### Key Concepts: 1. **Inner Circle**: This is the larger circle within which the smaller circles will be packed.
