Perhaps you should try some spelling variations:
"pulses estimation algorithms" » "pulses estimation algorithm", "pulses optimization algorithms", "pulses optimisation algorithm", "pose estimation algorithms"
"_ optimizer algorithms" » "_ optimized algorithms", "_ optimization algorithms", "_ optimize algorithms", "_ optimise algorithms"
"_ optimized algorithm" » "_ optimized algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ optimized algorithm") or ("_ optimizer algorithms"))) or ("pulses estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimized algorithm") OR ("_ optimizer algorithms"))) OR ("pulses estimation algorithms")).
• Removing quotes may allow a broader search: (((( _ optimized algorithm ) or ( _ optimizer algorithms ))) or ( pulses estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithm") or ("_ optimizer algorithms"))) or ("pulses estimation algorithms"))*.
