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