HCP-MAD:Heterogeneous Consensus-Progressive Reasoning for Efficient Multi-Agent Debate

arXiv:2604.09679v2 Announce Type: replace-cross Abstract: Multi-Agent Debate (MAD) is a collaborative framework in which multiple agents iteratively refine solutions through the generation of reasoning and alternating critique cycles. Current work primarily optimizes intra-round topologies and inter-round interactions separately, limiting the adaptation of token costs to task complexity. This work introduces Heterogeneous Consensus-Progressive Reasoning for Efficient Multi-Agent Debate (HCP-MAD), leveraging consensus as a dynamic signal to facilitate progressive reasoning. The core motivation

Why this matters
Why now

This paper addresses a known limitation in current Multi-Agent Debate frameworks by introducing a dynamic consensus mechanism, reflecting ongoing efforts to improve AI agent efficiency and cost-effectiveness.

Why it’s important

Improving the efficiency and adaptive intelligence of multi-agent systems is crucial for scaling AI applications and reducing operational costs across many industries.

What changes

The proposed HCP-MAD framework offers a more resource-efficient method for multi-agent reasoning, potentially accelerating the development and deployment of complex AI agent systems.
