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

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

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