Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"some optimized algorithm" » "some optimized algorithms", "some optimizer algorithms"

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 algorithm") or ((("_ estimation algorithms") or ("_ optimization algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("some optimized algorithm") OR ((("_ estimation algorithms") OR ("_ optimization algorithm"))))*.
• Removing quotes may allow a broader search: (( some optimized algorithm ) or ((( _ estimation algorithms ) or ( _ optimization algorithm ))))*.
