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