🏆 Scoring System

The tool uses the official eYRC marking formula:

Score = MaxMarks × (DeadEndsExplored/TotalDeadEnds) × min(OptimalSteps/ActualSteps, 1)

Given Maze (20 marks)

• Exploration Component: DeadEndsFound / 9
• Efficiency Component: min(112 / Steps, 1)

Surprise Maze (10 marks)

• Exploration Component: DeadEndsFound / 5
• Efficiency Component: min(110 / Steps, 1)

🔧 For Verilog Implementation

Recommended Algorithms

1. Left-Hand Rule - Most reliable for complete exploration
2. Right-Hand Rule - Alternative wall-following strategy
3. Random Mouse - Backup option (less predictable)

Implementation Notes

• Memory-free algorithms are ideal for hardware constraints
• Wall-following logic translates directly to sensor-based decisions
• Two-cycle timing must be considered for Verilog FSM design
• Complete dead-end exploration is crucial for maximum marks

🎯 Strategy for Full Marks

Based on analysis results:

1. Prioritize exploration over speed initially
2. Implement robust wall detection logic
3. Ensure systematic coverage of all dead ends
4. Optimize turn logic to minimize unnecessary moves
5. Test thoroughly with both maze configurations
