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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("over optimized algorithms") OR ("over optimized algorithm"))) OR ("qoe estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"over optimized algorithms\") OR (\"over optimized algorithm\"))) OR (\"qoe estimation algorithm\"))".
• Removing quotes may allow a broader search: (((( over optimized algorithms ) OR ( over optimized algorithm ))) OR ( qoe estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("over optimized algorithms") OR ("over optimized algorithm"))) OR ("qoe estimation algorithm"))*.
