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

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

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