Perhaps you should try some spelling variations:
"pulses estimation algorithms" » "pulses estimation algorithm", "pulses optimization algorithms", "pulses optimisation algorithm", "pose estimation algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization algorithms"
"_ optimizer algorithms" » "_ optimized algorithm", "_ optimization algorithms", "_ optimize 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 algorithms") OR ("_ optimizer algorithms"))) OR ("pulses estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimized algorithms\") OR (\"_ optimizer algorithms\"))) or (\"pulses estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) OR ( _ optimizer algorithms ))) or ( pulses estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") OR ("_ optimizer algorithms"))) or ("pulses estimation algorithms"))*.
