Perhaps you should try some spelling variations:
"qoe optimized algorithms" » "qoe optimized algorithm", "qoe optimizer algorithms", "qoe optimization algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"
"cover estimation algorithm" » "cover estimations algorithm", "pose estimation algorithm", "sphere estimation algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"cover estimation algorithm\") OR (((\"qoe optimized algorithms\") OR (\"_ optimized algorithms\"))))~".
• Removing quotes may allow a broader search: (( cover estimation algorithm ) OR ((( qoe optimized algorithms ) OR ( _ optimized algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("cover estimation algorithm") OR ((("qoe optimized algorithms") OR ("_ optimized algorithms"))))*.
