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"
"same optimized algorithms" » "same optimized algorithm", "same optimizer algorithms", "same optimization algorithms", "some optimized algorithms"

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

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