Agents coordinate indirectly via a shared state surface where results, hypotheses, and tasks are deposited rather than using direct chat. Typical conditions for use: Many agents contribute asynchronously; Shared state is more important than direct conversation. The central trade-off: Highly decoupled collaboration is achieved against demanding state manageme…
Use this profile to understand the building block briefly, place it in the model, and switch to the 360° assessment when needed.
Theoretical construct: explains a term, principle, or mental model.
What organizes, connects, or makes decisions possible.
The blackboard architecture coordinates specialized problem solvers through a shared knowledge store instead of relying entirely on direct messages.
The pattern was shaped in 1970s AI research for the Hearsay-II speech understanding system. It applies a shared workspace to cooperating knowledge sources and agents.
A blackboard holds hypotheses, tasks, and intermediate results. Knowledge sources read relevant entries, contribute findings, and trigger further processing.
The central idea and its purpose.
The essential building blocks work together.
Application depends on context and protection needs.
Blackboards suit asynchronous, incremental problem solving with several specialists. Access rules, prioritization, consistency, and stale hypotheses become central operating concerns.
