我需要学习如何设计DFA,以便给定任何数字'n',它接受二进制字符串{0,1},其十进制等效数可以被'n'整除.
不同的'n'会有不同的DFA,但有人可以给出一个基本的方法,我应该遵循任何数字0 <n <10.
我成功安装graphviz和cgraph使用
$ sudo pip install graphviz
....
Successfully installed graphviz-0.5.1
$ sudo pip install cgraph
...
Successfully installed cgraph-0.1
我No package 'libcgraph' found在跑步时遇到了这个问题sudo pip install pygraphviz.下面是完整的堆栈跟踪.
$ sudo pip install pygraphviz

The …import pygraphviz

我已经尝试过了
pip install pygraphviz --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"
我也试过这个答案,但仍然无法正常工作
我在macOS 10.10.5上安装pygraphviz时遇到了麻烦.我有一个功能齐全的Python 2.7.x安装,我想运行排队工具的测试示例,这需要使用pip安装pygraphviz.
执行命令时pip install pygraphviz,我收到以下冗长的错误消息:
