Perhaps you should try some spelling variations:
"qoe optimized algorithms" » "qoe optimized algorithm", "qoe optimization algorithms", "_ optimized algorithms"
"_ optimizer algorithms" » "_ optimized algorithm", "_ optimization algorithms", "_ optimized algorithms", "_ optimize algorithms", "_ optimise 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: (("qoe optimized algorithms") or ((("_ optimizer algorithms") or ("qoe estimation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("qoe optimized algorithms") OR ((("_ optimizer algorithms") OR ("qoe estimation algorithm")))).
• Removing quotes may allow a broader search: (( qoe optimized algorithms ) or ((( _ optimizer algorithms ) or ( qoe estimation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("qoe optimized algorithms") or ((("_ optimizer algorithms") or ("qoe estimation algorithm"))))*.
