A directed cyclic graph (DCG) permits cycles, in contrast to a directed acyclic graph (DAG); a DCG allows control flow between agents to form feedback loops, supporting iterative reasoning and dynamic adjustment.

UnverifiedThe overall execution graph of a Dify workflow must be a DAG (Directed Acyclic Graph) or a directed graph with controlled loops.67% similarUnverified与传统的DAG（有向无环图）不同，LangGraph支持循环（Cycles）66% similarUnverifiedThis node graph structure is known in computer science as a Directed Acyclic Graph (DAG), where "directed" means dependency relationships have a definite direction and "acyclic" means circular dependencies are not allowed.63% similarUnverifiedBoth Dify and n8n use directed acyclic graph (DAG) structures at their core to describe task dependencies, while ComfyUI allows cyclic nodes to support iterative optimization workflows.62% similarUnverifiedCompared with pure LLM-autonomy-driven loops, DAGs have the advantage of deterministic, predictable, and easily auditable execution paths, while their limitation is insufficient flexibility and the inability to dynamically adjust paths based on intermediate results at runtime.62% similar
