VerifiedThe StateGraph design of LangGraph is rooted in Finite State Machine (FSM) theory, but extends states to structured data objects rather than discrete enumerated values.76% similarUnverifiedLangGraph通过TypedDict或Pydantic模型定义状态Schema，并支持Reducer函数规定状态在节点间合并更新，例如消息列表用operator.add追加策略76% similarUnverified在 LangGraph 中，每个节点执行后返回的字典数据会被合并进全局 State 对象，State 的变化本质上就是状态转换72% similarUnverifiedLangGraph通过StateGraph维护不可变的状态对象，每次状态变更生成新的状态版本而非原地修改69% similarUnverifiedThe core model of an FSM consists of five elements: a set of states, an input alphabet, a transition function, an initial state, and an accept state.68% similar
