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