Swarm Type: MajorityVoting

​
Overview

The MajorityVoting swarm type implements a democratic decision-making process where multiple agents independently analyze a problem and propose solutions. The final outcome is determined by majority consensus, making this architecture ideal for scenarios where you want to leverage collective intelligence while maintaining a clear decision-making process. Key features:
  • Democratic Decision Making: Multiple agents vote on solutions
  • Consensus Building: Majority rule determines final outcome
  • Independent Analysis: Each agent works independently before voting
  • Transparent Process: Clear voting mechanism and results

​
Use Cases

  • Content quality assessment and approval
  • Problem diagnosis with multiple expert opinions
  • Decision-making in uncertain scenarios
  • Quality control and validation processes
