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