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