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

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: (("done optimized algorithm") OR ((("_ estimation algorithms") OR ("_ optimization algorithm"))))~.
• Removing quotes may allow a broader search: (( done optimized algorithm ) or ((( _ estimation algorithms ) or ( _ optimization algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("done optimized algorithm") or ((("_ estimation algorithms") or ("_ optimization algorithm"))))*.
