This algorithm attempts to minimise numerically. Because of this, the quality of the dither produced by Knoll’s algorithm is much higher than any other of the N-candidate methods we have covered so far. It is also the slowest however, as it requires a greater per-pixel to be really effective. More details are given in Knoll’s now expired patent[3]. I have put together a GPU implementation of Knoll’s algorithm on Shadertoy here.
Requires C++20. Axiom is the only dependency (included as a submodule).

随着2025年四季度外卖平台补贴力度收紧，行业逐渐向理性竞争回归，瑞幸也在主动调整策略以缓解盈利压力。事实上，瑞幸早在2024年就开始收紧9.9元低价活动覆盖范围，2025年进一步限制于少量基础款，多数产品回升至10.9-13.9元区间，通过优化定价策略平衡营收增长与盈利水平。这种调整背后，是瑞幸对“规模+盈利”双重目标的追求，也是行业从价格战向价值竞争转型的缩影。
