LangChain - LangGraph for Stateful AgentsWhy does Langchain use directed edges between nodes instead of undirected edges?ABecause nodes cannot connect to more than one nodeBTo represent one-way relationships and flow of informationCTo simplify the graph by removing connectionsDBecause undirected edges are not supported in any graphCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand the purpose of directed edgesDirected edges show direction, meaning one node leads to another.Step 2: Apply this to Langchain's graph useLangchain uses directed edges to model flow or one-way relationships clearly.Final Answer:To represent one-way relationships and flow of information -> Option BQuick Check:Directed edges = one-way flow [OK]Quick Trick: Directed edges show direction of relationships [OK]Common Mistakes:MISTAKESThinking undirected edges are unsupportedAssuming edges remove connectionsBelieving nodes have limited connections
