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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("qoe estimation algorithm") or ("_ estimation algorithms"))) or ("qoe optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe estimation algorithm") OR ("_ estimation algorithms"))) OR ("qoe optimized algorithms"))*.
• Removing quotes may allow a broader search: (((( qoe estimation algorithm ) or ( _ estimation algorithms ))) or ( qoe optimized algorithms ))*.
