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

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