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

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