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

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