Perhaps you should try some spelling variations:
"qoe optimization algorithm" » "qoe optimization algorithms", "qoe optimisation algorithm", "qoe estimation algorithms", "game optimization algorithm", "_ optimization algorithm", "stage optimization algorithm"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"game estimation algorithm" » "pose estimation algorithm", "game optimization algorithm"

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: (((("game estimation algorithm") OR ("qoe optimization algorithm"))) OR ("_ optimized algorithm"))~.
• Removing quotes may allow a broader search: (((( game estimation algorithm ) or ( qoe optimization algorithm ))) or ( _ optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("game estimation algorithm") or ("qoe optimization algorithm"))) or ("_ optimized algorithm"))*.
