Multi-Agent Minesweeper Solver with Google ADK

An advanced multi-agent AI system that collaboratively solves Minesweeper puzzles using Google's Agent Development Kit (ADK). This project demonstrates the power of agent orchestration, where specialized AI agents work together to tackle complex problem-solving tasks.

🎯 Project Overview

This project showcases autonomous multi-agent AI systems where three specialized agents collaborate to solve Minesweeper:

StrategistAgent: Performs high-level strategic analysis and constraint solving
ProbabilityAgent: Calculates advanced probabilities using constraint satisfaction
DecisionAgent: Makes optimal move decisions based on agent collaboration

🐛 Troubleshooting

Common Issues

Issue: ImportError: No module named 'agent_development_kit' Solution: Install ADK with pip install agent-development-kit

Issue: Google Cloud authentication error Solution: Run gcloud auth application-default login

Issue: Memory usage too high Solution: Reduce max_constraint_size in configuration

Issue: Solver gets stuck in infinite loop Solution: Increase max_moves or enable emergency moves
