We wanted a scenario where, say, 5 well-placed border points could efficiently represent an area with 5,000 internal points and 10,000 road edges. This would reduce those 10,000 edges to just 5*4/2 = 10 shortcuts for routing through that cluster at a high level – an incredible 1:1000 point ratio and a 30x reduction in edges to consider for the high-level path!
母亲每次和我通电话时很委屈，声音哽咽或干脆哭鼻子，嚷嚷着要回家。当然，养老院的餐食、床铺和服务，她都不挑剔。那里环境自然比家里好，我也想给她换一个单间住，但毕竟我们的经济条件不允许。我只能顺着母亲的“台阶”下，无可奈何将她接回家里。有我在家陪伴还好，我一旦外出工作，撇下妈妈，就是牵肠挂肚的不放心和焦虑。
