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.

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