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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("pulses optimization algorithms") or ((("_ optimizer algorithms") OR ("_ optimized algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("pulses optimization algorithms") OR ((("_ optimizer algorithms") OR ("_ optimized algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"pulses optimization algorithms\") or (((\"_ optimizer algorithms\") OR (\"_ optimized algorithm\"))))".
• Removing quotes may allow a broader search: (( pulses optimization algorithms ) or ((( _ optimizer algorithms ) OR ( _ optimized algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("pulses optimization algorithms") or ((("_ optimizer algorithms") OR ("_ optimized algorithm"))))*.
