Optimal circle packing
WebNov 12, 2012 · Packing efficiency The algorithm works quite poorly on identically-sized circles (it cannot find the famous honeycomb pattern for 20 circles in a square), but pretty well on a wide distribution of random radii. Aesthetics The result is pretty ungainly for identical-sized circles. WebJul 12, 2024 · Given a 1\times b rectangle R, we apply DSLP for packing the input circles into R. Theorem 1. Let b \ge 1. Any online sequence of circles with a total area no larger than \min \Big (0.528607 \cdot b - 0.457876,\frac {\pi } {4} \Big ) can be packed into the 1 \times b - rectangle R. This is worst-case optimal for b\ge 2.36.
