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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"pulses estimation algorithms\") OR (((\"_ optimized algorithm\") OR (\"_ optimizer algorithmss\"))))~".
• Removing quotes may allow a broader search: (( pulses estimation algorithms ) OR ((( _ optimized algorithm ) OR ( _ optimizer algorithmss ))))~.
• Adding a wildcard symbol may retrieve word variants: (("pulses estimation algorithms") OR ((("_ optimized algorithm") OR ("_ optimizer algorithmss"))))*.
