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 algorithmssssssss" » "parameters optimisation algorithmsssssss", "parameters estimation algorithmssssssss", "parameters estimation algorithmsssssss", "parameter optimization algorithmssssssss", "parameter estimation algorithmssssssss"

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