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