There’s an old puzzle that requires the solver to form as many whole numbers as possible, starting with 1, using only the digit 4 exactly four times, together with ordinary arithmetic and algebraic ...

Weighted automata extend classical finite automata by assigning weights, typically drawn from algebraic structures such as semirings, to transitions. This quantitative enhancement enables the analysis ...

Automata learning and formal verification represent converging fields aimed at enhancing the reliability and safety of complex systems. Automata learning involves the algorithmic inference of system ...
