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"
"parameter optimization algorithmssssssssss" » "parameter optimisation algorithmsssssssss", "parameter estimation algorithmssssssssss", "parameter estimation algorithmsssssssss", "parameters optimization algorithmssssssssss"

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

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