Plain language
A multi-agent system run by a single boss agent that hands out subtasks and collects everyone's results.
As stated in the literature
A centralized hierarchical multi-agent orchestration framework where a main controller decomposes tasks, writes sub-agent prompts, and synthesizes their reports; used as the primary baseline against DeLM's verified-shared-context approach, including a strengthened parallel variant.
Also called: AOrchestra-Parallel
Why it matters: It offers a clean way to coordinate many agents on a complex job, but it serves here as the comparison point that shows whether sharing verified context between agents works better than funneling everything through one controller.
For example, a single boss agent might split 'write a market report' into research, drafting, and fact-checking subtasks, assign each to a helper agent, and stitch their replies into one document.
