Considering non-deterministic PDAs, the superposition of states is possible by definition. However, non-deterministic PDAs have only one stack which cannot be in multiple states simultaneously. How is this possible?
To address the question regarding non-deterministic pushdown automata (PDAs) and the apparent paradox of state superposition with a single stack, it is essential to consider the fundamental principles of non-determinism and the operational mechanics of PDAs. A pushdown automaton is a computational model that extends the capabilities of finite automata by incorporating an auxiliary storage

How does a non-deterministic Turing machine represent multiple transitions for a given state and input symbol?
A non-deterministic Turing machine (NTM) is a theoretical model of computation that allows for multiple possible transitions from a given state and input symbol. This concept of non-determinism is a fundamental aspect of computational complexity theory and plays a important role in understanding the capabilities and limitations of Turing machines. In a non-deterministic Turing machine,
