📊 Enhanced Allocation Strategies

Mixed Strategy (Advanced v3.0)

• Multi-Pass Allocation: Three-phase optimization for maximum efficiency
• Spatial Awareness: 2D grid positioning for optimal subject separation
• Quality Scoring: Distribution and separation metrics
• Intelligent Quotas: Balanced subject distribution across rooms

Separated Strategy (Enhanced)

• Room-Level Distribution: Optimal subject grouping across rooms
• Intra-Room Optimization: Maximum separation within each room
• Adaptive Distance: Dynamic separation based on room capacity

🎯 Quality Metrics

• Distribution Score: Measures subject spread across seats (higher = better)
• Separation Score: Evaluates spatial separation using 2D coordinates
• Quality Ratings: Excellent, Very Good, Good, Fair, Needs Improvement
• Algorithm Tracking: Version monitoring for performance analysis

📄 Enhanced PDF Reports

• Dual Subject Columns: Primary subject + all subjects with smart formatting
• Quality Indicators: Room-level distribution and separation scores
• Professional Layout: Alternating colors, optimized typography, better spacing
• Intelligent Formatting: Subject grouping, name truncation, line breaks
