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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ 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"))*.
