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"
"game optimized algorithm" » "game optimized algorithms", "game optimizer algorithms", "same optimized algorithm"

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

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