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