How do Multi-Agent Debate and Consensus Protocols improve complex mathematical and coding reasoning?
❓ Interview Prompt: Explain Multi-Agent Debate, Delphi consensus methods, cross-agent critique, and eliminating individual model bias.
A single LLM instance is prone to confirmation bias and un-checked logical errors. Multi-Agent Debate Protocols leverage multiple independent agent instances that critique and refine each other's solutions over iterative rounds.
Debate Round Mechanics:
1
Generation Round: 3 independent agent instances (Agent A, B, C) generate solutions to a complex problem.
2
Cross-Critique Round: Each agent reads the solutions of the other two agents, pointing out logical errors or calculation flaws.
3
Consensus Voting: Agents revise their answers based on critiques until a supermajority consensus is reached.
4
Result: Significantly outperforms single-agent chain-of-thought on hard math and coding benchmarks!
Code Implementation Example
typescript
async function multiAgentDebate(problem: string, maxRounds: number = 2): Promise<string> {
let answers = await Promise.all([agentA.solve(problem), agentB.solve(problem), agentC.solve(problem)]);
for (let round = 0; round < maxRounds; round++) {
// Critique round: Pass peer answers to each agent
answers = await Promise.all([
agentA.refine(problem, answers),
agentB.refine(problem, answers),
agentC.refine(problem, answers)
]);
}
return selectMajorityAnswer(answers);
}💡Multi-Agent Debate protocol loop iterating cross-critique and consensus voting.
🎯 Interview Key Takeaway
Multi-agent debate protocols eliminate single-model bias by iterating peer cross-critiques and consensus voting.
