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