I'm working on an exercise (not relevant for evaluation) that involves constructing an equivalent nondeterministic stack machine from a given machine with epsilon-transitions. However, I'm having trouble understanding Definition 2, specifically the line
Could someone please explain this line and guide me via hints through the steps to construct the equivalent nondeterministic stack machine? I'm not asking for a solution, just for help.
Any help or guidance would be greatly appreciated!
Thank you.
