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

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