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