World Models: Explicit vs. Implicit Approaches
World models for agentic systems fall into two categories: hand-engineered simulators (explicit) offering consistency and debuggability but high adaptation cost, and implicit neural models offering flexibility but lacking verifiable long-horizon consistency. Our research targets a principled middle ground, combining the best of both worlds for adaptive, reliable, and verifiable models.
This approach addresses the limitations of both extremes, providing a scalable solution for complex, dynamic environments.
The DEVS Formalism: A Structured Foundation
We adopt the Discrete Event System Specification (DEVS) formalism as the operational representation for world models. DEVS decomposes systems into interacting atomic and coupled components, each with explicit state, transition, and timing semantics.
This modularity enables hierarchical system representation, clear event routing, and precise simulation semantics. It ensures consistency over long horizons and explicit timing/causality, critical for complex environments like queueing systems, distributed protocols, and multi-agent coordination.
DEVS-Based Model Generation Pipeline
Our approach introduces a staged LLM-based generation pipeline that synthesizes discrete-event simulators directly from natural-language specifications. This pipeline separates structural inference (component hierarchy, interactions) from component-level behavioral logic (event and timing).
This decomposition allows for parallel generation, reduces cross-component coupling, and improves robustness to local generation errors, making online adaptation feasible. Adaptive coupling ensures generated code remains consistent with architectural plans.
Trace-Based, Specification-Driven Evaluation
Traditional evaluation methods are ill-suited for generative models without unique ground truth. We propose a trace-based, specification-driven evaluation framework. Simulators emit structured event traces (time, entity, type, payload) that are validated against specification-derived temporal and semantic constraints.
This enables reproducible verification and localized diagnostics for rule violations, ensuring models are not just executable but also behaviorally conformant at both component and system levels, without relying on a reference implementation.

Case Study: Alternating Bit Protocol (ABP) Model
Overview: A standard implementation of the Alternating Bit Protocol (ABP) to achieve reliable data transmission over an unreliable channel, serving as a benchmark for precise algorithmic logic implementation.
Entities:
- Sender
- Receiver
- Subnets (Forward and Backward channels)
Dynamics:
- State Machine: Sender implements a 'Stop-and-Wait' FSM, sending packets and blocking until a valid ACK or timeout occurs.
- Deterministic Noise: Packet loss is governed by a Linear Congruential Generator (LCG), ensuring reproducible packet fate for rigorous testing.
