Abstract

We introduce ToPolyAgent, a multi-agent AI framework for performing coarse-grained molecular dynamics (MD) simulations of topological polymers through natural language instructions.

  • These papers typically split the workflow into role-specific agents for planning, structure retrieval, simulation execution, analysis, and quality control.

    “These papers typically split the workflow into role-specific agents for planning, structure retrieval, simulation execution, analysis, and quality control [18,19,21,25,26,35-38,41,42].”

    From From Scientific Copilots to Tool-Grounded Autonomy: AI Agents in Simulation-Driven Materials Discovery (2026) · cites this paper as [38]

    Section 2.1 (page not provided) describes role-specific Config, Simulation, Workflow, and Report Agents, including simulation execution and analysis. It does not describe agents for structure retrieval or quality control; Section 4 discusses a planning agent only as a possible future addition. Thus this paper supports the role-specific workflow in part, but not the full list attributed to it. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Some studies are simulator-native: the agent configures or executes atomistic or thermodynamic tools directly.

    “Some studies are simulator-native: the agent configures or executes atomistic or thermodynamic tools directly [21,25,28,29,31,33,36,38-42].”

    From From Scientific Copilots to Tool-Grounded Autonomy: AI Agents in Simulation-Driven Materials Discovery (2026) · cites this paper as [38]

    Section 2.2 (Tools for Agents) says the runLAMMPS tool executes simulations using parameters supplied by the agent, supporting the simulator-native part of the claim. Section 2.3 (Molecular Dynamics) specifies that these are coarse-grained bead-spring polymer simulations; it does not describe the tools as atomistic or specifically thermodynamic. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Other papers were more demonstrative, emphasizing workflow feasibility, design navigation, or case-based success rather than tightly standardized metrics.

    “Other papers were more demonstrative, emphasizing workflow feasibility, design navigation, or case-based success rather than tightly standardized metrics [17,18,21,22,35,37-39,41].”
  • Papers such as SmartCIF, DynaMate, VASPilot, Matty, GENIUS, and ToPolyAgent show that a substantial share of the current advance lies not in replacing scientific judgment with text generation, but in making brittle infrastructural steps programmable and recoverable.

    “Papers such as SmartCIF, DynaMate, VASPilot, Matty, GENIUS, and ToPolyAgent show that a substantial share of the current advance lies not in replacing scientific judgment with text generation, but in making these brittle infrastructural steps programmable and recoverable [21,25,37-39,42].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
