Perhaps you should try some spelling variations:
"cost optimized algorithms" » "cost optimizer algorithms", "cost optimization algorithms", "cost optimizer algorithmss", "most optimized algorithms"
"cost optimized algorithm" » "cost optimizer algorithms", "most optimized algorithm"
"qoe estimation algorithm" » "pose estimation algorithm", "_ estimation algorithm", "cover estimations algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("cost optimized algorithm") OR ("cost optimized algorithms"))) or ("qoe estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("cost optimized algorithm") OR ("cost optimized algorithms"))) OR ("qoe estimation algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cost optimized algorithm\") OR (\"cost optimized algorithms\"))) or (\"qoe estimation algorithm\"))".
• Removing quotes may allow a broader search: (((( cost optimized algorithm ) OR ( cost optimized algorithms ))) or ( qoe estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("cost optimized algorithm") OR ("cost optimized algorithms"))) or ("qoe estimation algorithm"))*.
