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