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