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