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

You may be able to get more results by adjusting your search query.

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