UnverifiedLangGraph将FSM的状态概念扩展为可携带任意数据的TypedDict对象，每个节点执行后返回状态的增量更新，由框架负责合并76% 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74% similarUnverifiedLangGraph将图状态机与LLM推理相结合，节点是工具或LLM调用，边是条件转移逻辑，通过持久化层（Checkpoint）保证流程可中断恢复68% similarUnverifiedLangGraph 在表达能力上超越经典有限状态机，更接近下推自动机或 Petri 网的计算模型67% similarUnverifiedLangGraph 的边分为普通边（无条件跳转）和条件边（根据当前状态值动态决定路由目标），条件边是实现分支逻辑的核心机制65% similar
