Perhaps you should try some spelling variations:
"_ optimizer algorithmss" » "_ optimizer algorithms", "_ optimized algorithms", "_ optimized algorithmss", "_ optimize algorithmss", "_ optimise algorithmss"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms", "_ optimized algorithm"
"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.

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