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