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

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"done optimized algorithm\") OR (\"don optimized algorithms\"))) OR (\"_ optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( done optimized algorithm ) OR ( don optimized algorithms ))) OR ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithm") OR ("don optimized algorithms"))) OR ("_ optimisation algorithm"))*.
