NFA Branch

An NFA (Nondeterministic Finite Automaton) branch refers to the multiple possible paths that can be taken when processing an input string. In an NFA, at any step, the machine can choose to follow different transitions for the current input symbol or even move without consuming any input (epsilon transitions). This means the automaton can be in multiple states simultaneously, exploring various options in parallel. When the input is fully read, if any of these paths reach an accepting state, the string is considered accepted. This branching capability makes NFA a flexible model for recognizing patterns in strings.
