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"

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