3.2 Optimization Strategies

This section outlines the optimization strategies implemented to enhance the performance, efficiency, and reliability of the Neural Snake AI system.

3.2.1 Neural Network Optimization

1. Weight Optimization

   class NetworkOptimizer {
       // Implement batch normalization
       batchNormalize(layer) {
           const mean = layer.reduce((a, b) => a + b) / layer.length;
           const variance = layer.reduce((a, b) => a + Math.pow(b - mean, 2)) / layer.length;
           return layer.map(value => (value - mean) / Math.sqrt(variance + 1e-8));
       }
   
       // Implement dropout for regularization
       applyDropout(layer, rate = 0.5) {
           const mask = layer.map(() => Math.random() > rate ? 1 / (1 - rate) : 0);
           return layer.map((value, i) => value * mask[i]);
       }
   
       // Optimize learning rate
       adaptiveLearningRate(iteration, baseRate = 0.1) {
           return baseRate / (1 + 0.01 * iteration);
       }
   }

2. Memory Management

   class MemoryOptimizer {
       constructor(maxCacheSize = 1000) {
           this.cache = new LRUCache(maxCacheSize);
           this.weightHistory = [];
       }
   
       // Implement weight pruning
       pruneWeights(weights, threshold = 0.01) {
           return weights.map(w => Math.abs(w) < threshold ? 0 : w);
       }
   
       // Optimize cache usage
       manageCache() {
           if (this.cache.size > this.cache.maxSize * 0.9) {
               this.cache.prune();
           }
       }
   }

3.2.2 Game Engine Optimization

1. Rendering Optimization

   class RenderOptimizer {
       constructor(canvas) {
           this.canvas = canvas;
           this.ctx = canvas.getContext('2d');
           this.offscreenCanvas = new OffscreenCanvas(canvas.width, canvas.height);
           this.offscreenCtx = this.offscreenCanvas.getContext('2d');
       }
   
       // Double buffering implementation
       render(gameState) {
           // Draw to offscreen canvas
           this.drawToOffscreen(gameState);
           
           // Swap buffers
           this.ctx.drawImage(this.offscreenCanvas, 0, 0);
       }
   
       // Partial updates
       updateRegion(x, y, width, height) {
           this.ctx.drawImage(
               this.offscreenCanvas,
               x, y, width, height,
               x, y, width, height
           );
       }
   }

2. Physics Optimization

   class PhysicsOptimizer {
       // Spatial partitioning for collision detection
       setupGrid(worldSize, cellSize) {
           this.grid = new Array(Math.ceil(worldSize / cellSize))
               .fill(null)
               .map(() => new Set());
       }
   
       // Optimized collision detection
       checkCollisions(entity) {
           const cell = this.getCell(entity.position);
           return Array.from(this.grid[cell])
               .filter(other => this.distance(entity, other) < entity.radius + other.radius);
       }
   }

3.2.3 Blockchain Integration Optimization

1. Transaction Processing

   class TransactionOptimizer {
       // Batch processing implementation
       async processBatch(transactions) {
           const validTransactions = await Promise.all(
               transactions.map(tx => this.validateTransaction(tx))
           );
   
           return validTransactions
               .filter(tx => tx.valid)
               .map(tx => this.generateMoveCommand(tx));
       }
   
       // Connection pool management
       optimizeConnections() {
           this.pool.forEach(conn => {
               if (conn.idle > this.maxIdleTime) {
                   conn.close();
               }
           });
       }
   }

2. State Synchronization

   class StateOptimizer {
       // Differential state updates
       generateStateDiff(oldState, newState) {
           return Object.entries(newState).reduce((diff, [key, value]) => {
               if (oldState[key] !== value) {
                   diff[key] = value;
               }
               return diff;
           }, {});
       }
   
       // Compression implementation
       compressState(state) {
           return LZString.compress(JSON.stringify(state));
       }
   }

3.2.4 Performance Monitoring

class PerformanceMonitor {
    constructor() {
        this.metrics = {
            fps: new MovingAverage(60),
            memoryUsage: new MovingAverage(60),
            networkLatency: new MovingAverage(60)
        };
    }

    // Monitor frame rate
    measureFPS() {
        const now = performance.now();
        const fps = 1000 / (now - this.lastFrame);
        this.metrics.fps.add(fps);
        this.lastFrame = now;
    }

    // Monitor memory usage
    trackMemory() {
        if (performance.memory) {
            this.metrics.memoryUsage.add(performance.memory.usedJSHeapSize);
        }
    }

    // Generate performance report
    generateReport() {
        return {
            averageFPS: this.metrics.fps.getAverage(),
            memoryTrend: this.metrics.memoryUsage.getTrend(),
            networkHealth: this.metrics.networkLatency.getStats()
        };
    }
}

3.2.5 Resource Management

1. Asset Loading

   class AssetManager {
       // Progressive loading
       async loadAssets(assets) {
           const critical = assets.filter(a => a.priority === 'high');
           const nonCritical = assets.filter(a => a.priority !== 'high');
   
           await Promise.all(critical.map(this.loadAsset));
           this.startGame();
           
           // Load non-critical assets in background
           nonCritical.forEach(asset => {
               this.loadAsset(asset).then(() => this.updateAsset(asset));
           });
       }
   
       // Asset caching
       cacheAsset(asset) {
           if (this.cache.size > this.maxCacheSize) {
               const leastUsed = this.findLeastUsedAsset();
               this.cache.delete(leastUsed);
           }
           this.cache.set(asset.id, asset);
       }
   }

2. Memory Management

   class MemoryManager {
       // Garbage collection optimization
       optimizeMemory() {
           this.clearUnusedCache();
           this.disposeUnusedTextures();
           this.cleanupEventListeners();
       }
   
       // Resource pooling
       getFromPool(type) {
           if (this.pools[type].length === 0) {
               this.expandPool(type);
           }
           return this.pools[type].pop();
       }
   }

These optimization strategies work together to ensure the system operates at peak efficiency while maintaining reliability and responsiveness. Regular monitoring and adjustment of these optimizations ensure continued performance improvements over time.
