Perhaps you should try some spelling variations:
"qoe optimized algorithms" » "qoe optimizer algorithms", "qoe optimization algorithms", "qoe optimizer algorithmss", "_ optimized algorithms"
"qoe optimized algorithm" » "qoe optimizer algorithms", "_ optimized algorithm"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation 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: (("post estimation algorithm") or ((("qoe optimized algorithm") OR ("qoe optimized algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("post estimation algorithm") OR ((("qoe optimized algorithm") OR ("qoe optimized algorithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"post estimation algorithm\") or (((\"qoe optimized algorithm\") OR (\"qoe optimized algorithms\"))))".
• Removing quotes may allow a broader search: (( post estimation algorithm ) or ((( qoe optimized algorithm ) OR ( qoe optimized algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("post estimation algorithm") or ((("qoe optimized algorithm") OR ("qoe optimized algorithms"))))*.
