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