Master DFA Minimization: Step-by-Step Algorithm & Example 🛠️

Here we consider the problem of minimizing the number of states in a deterministic finite automaton (DFA). The key here is to identify pairs of states that are "distinguishable", in the sense that reading any string from both of them eventually will lead to an accept state in one case, and a non-accept state in the other case. Then we build the definition of distinguishable states recursively. We conclude with two examples of DFAs: one where no states can be removed, and another where multiple states can be removed.
