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