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

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