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