Perhaps you should try some spelling variations:
"cong optimized algorithms" » "cong optimizer algorithms", "cong optimization algorithms", "cong optimizer algorithmss"
"dong optimized algorithm" » "dong optimizer algorithms", "dung optimized algorithm"
"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: (((("cong optimized algorithms") OR ("dong optimized algorithm"))) OR ("qoe estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cong optimized algorithms\") OR (\"dong optimized algorithm\"))) OR (\"qoe estimation algorithm\"))".
• Removing quotes may allow a broader search: (((( cong optimized algorithms ) OR ( dong optimized algorithm ))) OR ( qoe estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("cong optimized algorithms") OR ("dong optimized algorithm"))) OR ("qoe estimation algorithm"))*.
