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

Try widening your search to All Fields.

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

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