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