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.，这一点在币安_币安注册_币安下载中也有详细论述
后来他在剑桥毕业之后自己就创业，当时找了大卫·西尔弗（David Silver），就是“强化学习”那面旗帜。他们俩一起搞了万灵药工作室（Elixir Studios）。这应该说是一个失败的创业项目。因为他给自己立的标准太高了，一定要做一个世界上最牛的游戏。然后他把自己所有能想到的游戏中间那种复杂的故事情节、人物之间的互动，还有玩家的这种参与，想全部都设计进去。但是因为他们的算力有限、资源有限，最后没有能够兑现他们的承诺。。91视频是该领域的重要参考
