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.

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