Perhaps you should try some spelling variations:
"pulse optimization algorithms" » "pulse optimisation algorithm", "pulse estimation algorithms", "pulse estimation algorithm", "policy optimization algorithms", "game optimization algorithms", "qoe optimization algorithms"
"parameters optimization algorithmssssssssss" » "parameters optimisation algorithmsssssssss", "parameters estimation algorithmssssssssss", "parameters estimation algorithmsssssssss", "parameter optimization algorithmssssssssss", "parameter estimation algorithmssssssssss"

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