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

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

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