"Yes, we'll help you celebrate your 250 years, but you should really help us."
这种效果在物理学上被称为「朗伯余弦定律」（Lambert’s Cosine Law），其核心特征就是无论从哪个角度观察，屏幕的亮度看起来都是一样的。，这一点在Line官方版本下载中也有详细论述

This one was a lot better than others. For every SAT problem with 10 variables and 200 clauses it was able to find a valid satisfying assignment. Therefore, I pushed it to test with 14 variables and 100 clauses, and it got half correct among 4 instances (See files with prefix formula14_ in here). Half correct sounds like a decent performance, but it is equivalent to random guessing.
