    • normalizedFunctions = numFunctions / 200 (assuming max 200 functions for advanced apps)
    • normalizedSize = (500 - appSizeMB) / 500 (smaller size is better, max 500MB)
    • normalizedRating = userRating / 5 (max 5 stars)
    • normalizedAds = (20 - adFrequency) / 20 (fewer ads is better, max 20 ads/hr)
    • normalizedOffline = offlineCapability (1 for Yes, 0 for No)
    • normalizedBattery = (3 - batteryImpact) / 2 (Low=1, Medium=2, High=3; lower impact is better, scaled to 0-1)
  2. Calculate Component Scores:
    • Feature Richness Score: (normalizedFunctions * 0.4) + (normalizedOffline * 0.6)
    • Performance Impact Score: (normalizedSize * 0.5) + (normalizedBattery * 0.5)
    • User Satisfaction Index: (normalizedRating * 0.7) + (normalizedAds * 0.3)
  3. Calculate Overall Utility Score: The component scores are then weighted and summed to produce the final score.
    • overallScore = (featureRichnessScore * 0.4) + (performanceImpactScore * 0.3) + (userSatisfactionIndex * 0.3)
    • The final score is then multiplied by 100 for a percentage-like representation.
