This repository contains my solutions to some Circle Packing problems. The solutions are optimized using the Ring2D software. They are as close to optimal as the algorithms can provide.

Hexagonal lattice is not the only one when circles are packed in recangular container. Different number of circles and rectangle height result in different arrangement.
