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