Class BlackboardStrategy

Namespace

JD.AI.Core.Agents.Orchestration.Strategies

Assembly

JD.AI.Core.dll

Blackboard strategy — agents operate on a shared knowledge base (the scratchpad) in iterative rounds. Each round, agents read the current blackboard state, contribute their analysis, and write results back. Converges when no agent contributes new information or max iterations reached. Good for: complex analysis, multi-perspective investigation, knowledge synthesis.
