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

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 algorithms\") OR (\"_ optimized algorithms\"))) OR (\"_ optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( done optimized algorithms ) OR ( _ optimized algorithms ))) OR ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithms") OR ("_ optimized algorithms"))) OR ("_ optimisation algorithm"))*.
