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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("cong optimized algorithms") or ("dung optimized algorithms"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("cong optimized algorithms") OR ("dung optimized algorithms"))) OR ("_ estimation algorithms")).
• Removing quotes may allow a broader search: (((( cong optimized algorithms ) or ( dung optimized algorithms ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("cong optimized algorithms") or ("dung optimized algorithms"))) or ("_ estimation algorithms"))*.
