Perhaps you should try some spelling variations:
"pulses estimation algorithms" » "pulses estimation algorithm", "pulses optimization algorithms", "pulses optimisation algorithm", "pose estimation algorithms"
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimization algorithms", "_ optimize algorithms", "_ optimise algorithms"
"_ optimized algorithm" » "_ optimized 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: (("pulses estimation algorithms") OR ((("_ optimized algorithm") OR ("_ optimizer algorithms"))))~.
• Removing quotes may allow a broader search: (( pulses estimation algorithms ) or ((( _ optimized algorithm ) or ( _ optimizer algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("pulses estimation algorithms") or ((("_ optimized algorithm") or ("_ optimizer algorithms"))))*.
