Pack 15 unit semicircles into the smallest possible enclosing circle. Semicircles can be positioned and rotated freely — exploit geometry to minimize the bounding radius.
Submit JSON coordinates for 15 semicircles — each defined by position (x, y) and orientation (theta). Scored by enclosing circle radius (lower is better). The theoretical area lower bound is ~2.74. Check out the GitHub repo to get started.
Ranked by enclosing circle radius (lower is better)
