Pits and Orbs is an open-source reinforcement learning environment implemented in Python, offering a turn-based multi-agent grid-world where agents pursue objectives and face environmental hazards. Each agent must navigate a customizable grid, avoid randomly placed pits that penalize or terminate episodes, and collect orbs for positive rewards. The environment supports both competitive and cooperative modes, enabling researchers to explore varied learning scenarios. Its simple API integrates seamlessly with popular RL libraries like Stable Baselines or RLlib. Key features include adjustable grid dimensions, dynamic pit and orb distributions, configurable reward structures, and optional logging for training analysis.

RL Shooter is a Python-based framework that integrates ViZDoom with OpenAI Gym APIs to create a flexible reinforcement learning environment for FPS games. Users can define custom scenarios, maps, and reward structures to train agents on navigation, target detection, and shooting tasks. With configurable observation frames, action spaces, and logging facilities, it supports popular deep RL libraries such as Stable Baselines and RLlib, enabling clear performance tracking and reproducibility across experiments.

This repository implements emergent communication in multi-agent reinforcement learning using PyTorch. Users can configure sender and receiver neural networks to play referential games or cooperative navigation, encouraging agents to develop a discrete or continuous communication channel. It offers scripts for training, evaluation, and visualization of learned protocols, along with utilities for environment creation, message encoding, and decoding. Researchers can extend it with custom tasks, modify network architectures, and analyze protocol efficiency, fostering rapid experimentation in emergent agent communication.
