Perhaps you should try some spelling variations:
"dung optimized algorithm" » "dung optimized algorithms", "dung optimizer algorithms"
"don optimized algorithm" » "don optimized algorithms", "don optimizer algorithms", "_ optimized algorithm"
"cover estimation algorithm" » "cover estimations algorithm", "pose estimation algorithm", "sphere estimation algorithm"

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 algorithm") or ("don optimized algorithm"))) or ("cover estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("dung optimized algorithm") OR ("don optimized algorithm"))) OR ("cover estimation algorithm")).
• Removing quotes may allow a broader search: (((( dung optimized algorithm ) or ( don optimized algorithm ))) or ( cover estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("dung optimized algorithm") or ("don optimized algorithm"))) or ("cover estimation algorithm"))*.
