Perhaps you should try some spelling variations:
"qoe estimation algorithms" » "qoe estimation algorithm", "qoe optimization algorithms", "qoe optimisation algorithm", "pose estimation algorithms", "cover estimations algorithms"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimized algorithm", "_ optimization algorithms", "_ optimize algorithms", "_ optimise 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 ((("_ estimation algorithms") or ("_ optimizer algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("qoe estimation algorithms") OR ((("_ estimation algorithms") OR ("_ optimizer algorithms")))).
• Removing quotes may allow a broader search: (( qoe estimation algorithms ) or ((( _ estimation algorithms ) or ( _ optimizer algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("qoe estimation algorithms") or ((("_ estimation algorithms") or ("_ optimizer algorithms"))))*.
