+26 圆填圆，基线 0.9598（圆心按同心环写死、半径逐对缩放），已知最好 2.635983。同类系统和参考项目的高分运行，大多沿着这样一条路往上走：结构化的起点或多起点 → 把圆心和半径一起交给连续优化器 → 在当前最好解附近加扰动再优化，或退火式接受 → 最后修到严格合法。辅助手段有：固定圆心用线性规划求最优半径、只动贴紧的那几个圆。死路有：只做几何构造（圆心按手排的规则摆、不移动），各系统都卡在 2.2–2.54；只改半径的分法、不动圆心，上限受布局限制。这是常见的一条路，不是唯一正确的路：一条清单上没有、但讲得通的路，同样算往前走了。第 1 轮能走多远取决于起点，参考项目第 1 轮采纳的分数在 1.55 到 2.632 之间。
