LangChain - LangGraph for Stateful AgentsIn Langchain, what is typically used to decide which node to route to next in a graph?AA random number generatorBA condition function returning True or FalseCA fixed node index without conditionsDA user input prompt at runtimeCheck Answer
Step-by-Step SolutionSolution:Step 1: Identify routing mechanismRouting decisions depend on condition functions that return True or False based on context.Step 2: Evaluate optionsOnly the condition function returning True or False matches; others are unrelated or manual inputs.Final Answer:A condition function returning True or False -> Option BQuick Check:Routing decision = Condition function [OK]Quick Trick: Routing uses condition functions returning True/False [OK]Common Mistakes:MISTAKESAssuming routing is randomThinking routing is fixed without conditionsConfusing user input with routing logic
