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