### Hopcroft-Karp算法
该算法由John.E.Hopcroft和Richard M.Karp于1973提出,故称Hopcroft-Karp算法。
**原理**
为了降低时间复杂度,可以在增广匹配集合M时,每次寻找多条增广路径。这样就可以进一步降低时间复杂度,可以证明,算法的时间复杂度可以到达O(n^0.5*m),虽然优化不了多少,但在实际应用时,效果还是很明显的。…

It would be great if there could be few comments here and there on how to use the HopcroftKarp code for someone who knows what the algorithm is and how it works. Specifically, please explain: `size_u,…

`hash`, `isequal` and `==` are currently unable to handle self-referential recursive structures:
```
A=Any[]; push!(A,A); B=deepcopy(A);
isequal(A,B)
A==A

```
all give `StackOverflowErr…

I read some files in `lexer/dfa` but it seems lalrpop does not contain any code about minimizing dfa (e.g. Hopcroft's algorithm).
Is there any reason to not implement it?
