UnverifiedLangGraph 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81% similarUnverifiedLangGraph combines graph state machines with LLM reasoning, where nodes are tool or LLM calls and edges are conditional transition logic, with a persistence layer (Checkpoint) ensuring that processes can be interrupted and resumed.70% similarUnverifiedLangGraph借鉴了Pregel图计算模型，支持有状态的循环执行，更适合需要反复迭代的代理工作流69% similarVerifiedLangGraph supports stateful cyclic graphs (Cyclic Graph), which distinguishes it from pure DAGs; this is crucial for Agent reasoning loops that require repeated iteration.66% similarUnverifiedLangGraph中每个节点是一个纯函数，接收当前状态并输出状态更新，使系统具备可测试性和可观测性64% similar
