CArtAgO (Common ARTifact Infrastructure for AGents Open environments) is a lightweight, extensible framework for implementing environment infrastructures in multi-agent systems. It introduces the concept of artifacts: first-class entities representing environment resources with defined operations, observable properties, and event interfaces. Developers define artifact types in Java, register them in environment classes, and expose operations and events for agent consumption. Agents interact with artifacts using standard actions (e.g., createArtifact, observe), receive asynchronous notifications of state changes, and coordinate through shared resources. CArtAgO integrates easily with agent platforms such as Jason, JaCaMo, JADE, and Spring Agent, enabling hybrid system development. The framework provides built-in support for artifact documentation, dynamic loading, and runtime monitoring, facilitating rapid prototyping of complex agent-based applications.

MAGAIL implements a multi-agent extension of Generative Adversarial Imitation Learning, enabling groups of agents to learn coordinated behaviors from expert demonstrations. Built in Python with support for PyTorch (or TensorFlow variants), MAGAIL consists of policy (generator) and discriminator modules that are trained in an adversarial loop. Agents generate trajectories in environments like OpenAI Multi-Agent Particle Environment or PettingZoo, which the discriminator uses to evaluate authenticity against expert data. Through iterative updates, policy networks converge to expert-like strategies without explicit reward functions. MAGAIL’s modular design allows customization of network architectures, expert data ingestion, environment integration, and training hyperparameters. Additionally, built-in logging and TensorBoard visualization facilitate monitoring and analysis of multi-agent learning progress and performance benchmarks.
