Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"dong optimized algorithms" » "dong optimized algorithm", "dong optimization algorithms", "cong optimized algorithms", "dung optimized algorithms"
"dong optimizer algorithms" » "dong optimized algorithm", "dong optimization algorithms", "cong optimizer algorithms", "dung optimizer algorithms"

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: (((("dong optimized algorithms") OR ("dong optimizer algorithms"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("dong optimized algorithms") OR ("dong optimizer algorithms"))) OR ("_ estimation algorithms")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"dong optimized algorithms\") OR (\"dong optimizer algorithms\"))) or (\"_ estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( dong optimized algorithms ) OR ( dong optimizer algorithms ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("dong optimized algorithms") OR ("dong optimizer algorithms"))) or ("_ estimation algorithms"))*.
