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

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