上面的这个案例文法所产生的语言L(G)=L(0^ { * }(\epsilon+1+11))(这里使用了正则表达式),也就是说L(G)是一个RL,但不能说文法产生的语言都是RL,很容易可以举出文法G=(\{A\},\{0,1\},\{A\rightarrow 01|0A1\},A),它所产生的语言是\{0^n1^n|n\geq 1\},根据正则语言的泵引理,可以发现...
Finally, the heart of the SDK is its C compiler, capable of producing very tight, and quite effective, code. The unique feature of the underlying virtual machine is its ability to operate upon registers (vs. "top of stack" for virtually any other vm, including that of JavaTM); this add...
Push the current input symbol into the stack. Replace the right-hand side of a production at the top of the stack with its left-hand side. If the top of the stack element matches with the current input symbol, pop it. If the input string is fully read and only if the start symbol ...
Γ——栈符号表 (stack alphabet)。∀A∈Γ,叫做一个栈符号; Z0——Z0∈Γ叫做开始符号(start symbol),是 M 启动时候栈内惟一的一个符号。所以,习惯地称其为栈底符号; q0——q0∈Q,是 M 的开始状态(initial state),也可叫做初始状态或者启动状态; ...

When the last program identified on the stack has completed execution, the last program entry record is popped off of the stack. Thereafter, control is returned to an application that corresponds to the new program entry record on the top of the stack.チタンバラン ネンマーラ...
