Detailed Description

A workflow that runs multiple tasks in parallel.

This workflow allows LLMs to work simultaneously on a task and have their outputs aggregated. It supports two key variations:

• Sectioning: Breaking a task into independent subtasks run in parallel
• Voting: Running the same task multiple times to get diverse outputs

Member Enumeration Documentation

Strategy

enum class agents::workflows::ParallelizationWorkflow::Strategy

strong

Enum for parallelization strategy.

Note

This is an enum for the parallelization strategy. It contains the SECTIONING and VOTING strategies.

Enumerator
SECTIONING	Break task into independent subtasks.
VOTING	Run same task multiple times for consensus.
