7月1日，甘肃天水麦积区褐石培心幼儿园因违规使用添加剂，导致上百名幼儿血铅异常甚至中毒的事件引发全国关注。官方通报称，事件原因是幼儿园提供的三色枣发糕、玉米肠卷等食品中的添加剂超标。期间，因天水当地检测结果与幼儿在西安、上海等地异地就医检测结果差异悬殊、天水过往曾发生同类铅中毒事件等因素，引发争议与疑虑。

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.
