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

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

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