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

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 ((("_ optimize algorithm") or ("_ optimiser algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("pulses optimization algorithms") OR ((("_ optimize algorithm") OR ("_ optimiser algorithms")))).
• Removing quotes may allow a broader search: (( pulses optimization algorithms ) or ((( _ optimize algorithm ) or ( _ optimiser algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("pulses optimization algorithms") or ((("_ optimize algorithm") or ("_ optimiser algorithms"))))*.
