Perhaps you should try some spelling variations:
"dung optimized algorithms" » "dung optimizer algorithms", "dung optimization algorithms", "dung optimizer algorithmss"
"dong optimized algorithm" » "dong optimizer algorithms", "cong 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: (((("dung optimized algorithms") or ("dong optimized algorithm"))) or ("qoe estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("dung optimized algorithms") OR ("dong optimized algorithm"))) OR ("qoe estimation algorithm")).
• Removing quotes may allow a broader search: (((( dung optimized algorithms ) or ( dong optimized algorithm ))) or ( qoe estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("dung optimized algorithms") or ("dong optimized algorithm"))) or ("qoe estimation algorithm"))*.
