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

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

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