Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"done optimizer algorithms" » "done optimized algorithm", "done optimization algorithms", "dong optimizer algorithms", "one optimizer algorithms"
"don optimized algorithms" » "don optimized algorithm", "don optimization algorithms", "_ optimized 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 optimizer algorithms") or ("don optimized algorithms"))) or ("_ optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("done optimizer algorithms") OR ("don optimized algorithms"))) OR ("_ optimisation algorithm")).
• Removing quotes may allow a broader search: (((( done optimizer algorithms ) or ( don optimized algorithms ))) or ( _ optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("done optimizer algorithms") or ("don optimized algorithms"))) or ("_ optimisation algorithm"))*.
