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"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

You may be able to get more results by adjusting your search query.

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