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

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