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