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