Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"done optimized algorithms" » "done optimized algorithm", "done optimizer algorithms", "done optimization algorithms", "dong optimized algorithms", "one optimized algorithms"
"don optimized algorithms" » "don optimized algorithm", "don optimizer algorithms", "don optimization algorithms", "_ optimized 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 (\"don optimized algorithms\"))) OR (\"_ estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( done optimized algorithms ) OR ( don optimized algorithms ))) OR ( _ estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("done optimized algorithms") OR ("don optimized algorithms"))) OR ("_ estimation algorithms"))*.
