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"

Try widening your search to All Fields.

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"))))*.
