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"

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: (((("done optimized algorithm") OR ("dong optimized algorithm"))) or ("_ optimisation algorithm"))~.
• 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"))*.
