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

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