Perhaps you should try some spelling variations:
"qoe optimization algorithms" » "qoe optimisation algorithm", "qoe estimation algorithms", "qoe estimation algorithm", "game optimization algorithms", "_ optimization algorithms", "stage optimization algorithms"
"_ optimized algorithms" » "_ optimizer algorithms", "_ optimizer algorithmss"
"qoe optimized algorithm" » "qoe 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: (((("_ optimized algorithms") OR ("qoe optimized algorithm"))) OR ("qoe optimization algorithms"))~.
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) or ( qoe optimized algorithm ))) or ( qoe optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") or ("qoe optimized algorithm"))) or ("qoe optimization algorithms"))*.
