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

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

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