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