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