Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"done optimized algorithms" » "done optimizer algorithms", "done optimization algorithms", "done optimizer algorithmss"
"done optimized algorithm" » "done 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: (((("done optimized algorithms") OR ("done optimized algorithm"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("done optimized algorithms") OR ("done optimized algorithm"))) OR ("_ optimisation algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"done optimized algorithms\") OR (\"done optimized algorithm\"))) or (\"_ optimisation algorithm\"))".
• Removing quotes may allow a broader search: (((( done optimized algorithms ) OR ( done optimized algorithm ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithms") OR ("done optimized algorithm"))) or ("_ optimisation algorithm"))*.
