Multi-Agent LLMs

Last edited: March 3, 2026

Background

  1. originally, multi-agent team pre-assigns roles
  2. LLMs are heterogeneous, but they are treated homogeneously
  3. problem decomposition is hard

Eval

synergy

  • weak synergy: team >= average member
  • strong synergy: team >= best member

Human teams reliably achieve strong synergy IFF when expert identity is given (e.g., the teams easily know who is the expert).

Dataset

NASA moon survival / lost at seay

Rank 15 items by importance

Student body president

Different people are given different information + shared info. Hidden-profile (shared info + unique info must be paired to reveal the right one.)

convex-concave problems

Heuristic method for solving a specific type of non-convex problem. Solves a small sequence of convex problems.

difference-of-convex function

For:

\begin{equation} h\qty(x) = f\qty(x) - g\qty(x) \end{equation}

for convex \(f\qty(x)\) and \(g\qty(x)\).

some examples

  • a convex quadratic, except the \(P\) in \(\qty(\frac{1}{2}) x^{T}Px\) is not PSD; we express this in terms of \(P = P_{\text{psd}} - P_{\text{nsd}}\). And thus we can get: \(\qty(\frac{1}{2})x^{T}P_{\text{psd}} x - \qty(\frac{1}{2})x^{T}P_{\text{nsd}}x\)

majorization

Taylor approximation:
