Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"done optimized algorithm" » "done optimized algorithms", "done optimizer algorithms", "one optimized algorithm", "don optimized algorithm"
"dong optimized algorithm" » "dong optimized algorithms", "dong optimizer algorithms", "cong optimized algorithm", "dung 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 ("dong optimized algorithm"))) OR ("_ optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"done optimized algorithm\") OR (\"dong optimized algorithm\"))) or (\"_ optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( done optimized algorithm ) OR ( dong optimized algorithm ))) or ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithm") OR ("dong optimized algorithm"))) or ("_ optimisation algorithm"))*.
