Perhaps you should try some spelling variations:
"cover estimations algorithms" » "cover estimation algorithms", "cover estimation algorithm", "cover optimization algorithms", "pose estimation algorithms"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ 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: (((("qoe optimized algorithm") OR ("_ optimized algorithm"))) OR ("cover estimations algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimized algorithm\") OR (\"_ optimized algorithm\"))) or (\"cover estimations algorithms\"))~".
• Removing quotes may allow a broader search: (((( qoe optimized algorithm ) OR ( _ optimized algorithm ))) or ( cover estimations algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimized algorithm") OR ("_ optimized algorithm"))) or ("cover estimations algorithms"))*.
