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