统一正在把方便面从传统的“应急食品”重新塑造成一种更高品质的速食消费品。这背后反映的是，统一在方便面赛道的新生存哲学：不再盲目追求规模扩张，而是通过产品升级与渠道创新，在萎缩的市场总量中抢夺高价值份额。

NFAs are cheaper to construct, but have a O(n*m) matching time, where n is the size of the input and m is the size of the state graph. NFAs are often seen as the reasonable middle ground, but i disagree and will argue that NFAs are worse than the other two. they are theoretically “linear”, but in practice they do not perform as well as DFAs (in the average case they are also much slower than backtracking). they spend the complexity in the wrong place - why would i want matching to be slow?! that’s where most of the time is spent. the problem is that m can be arbitrarily large, and putting a large constant of let’s say 1000 on top of n will make matching 1000x slower. just not acceptable for real workloads, the benchmarks speak for themselves here.，更多细节参见51吃瓜
