UnverifiedComfyUI adopts a Directed Acyclic Graph (DAG) architecture, and its executor automatically analyzes the topological structure of the graph, recomputing only the node branches where changes have occurred (incremental execution).79% similarUnverified工作流编排的底层是有向无环图（DAG）数据结构，保证执行顺序确定性且不存在循环依赖76% similarUnverifiedThe overall execution graph of a Dify workflow must be a DAG (Directed Acyclic Graph) or a directed graph with controlled loops.73% similarUnverifiedTraditional ComfyUI workflows are strictly directed acyclic graphs (DAGs), where topological sorting guarantees that each node is executed only once and the execution order is uniquely determined.71% similarUnverified多智能体并行架构本质上是将链式推理拆解为有向无环图（DAG）式任务调度，可将整体完成时间从O(n)降至接近O(max_subtask)71% similar
