Perhaps you should try some spelling variations:
"post estimation algorithms" » "post optimization algorithms", "post optimisation algorithm", "post approximation algorithms", "pose estimation algorithms", "risk estimation algorithms", "pulses estimation algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation algorithm"

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

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