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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ optimized algorithm") or ((("qoe approximation algorithms") or ("qoe estimation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ optimized algorithm") OR ((("qoe approximation algorithms") OR ("qoe estimation algorithm")))).
• Removing quotes may allow a broader search: (( _ optimized algorithm ) or ((( qoe approximation algorithms ) or ( qoe estimation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithm") or ((("qoe approximation algorithms") or ("qoe estimation algorithm"))))*.
