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