Perhaps you should try some spelling variations:
"parameters optimization algorithmssssssssss" » "parameter optimization algorithmssssssssss", "parameter estimation algorithmssssssssss", "parameters optimisation algorithmsssssssss", "parameters estimation algorithmssssssssss", "parameters estimation algorithmsssssssss"
"same optimization algorithms" » "same optimisation algorithm", "same estimation algorithms", "same estimation algorithm", "game optimization algorithms", "stage 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: (("parameters optimization algorithmssssssssss") or ("same optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameters optimization algorithmssssssssss") OR ("same optimization algorithms")).
• Removing quotes may allow a broader search: (( parameters optimization algorithmssssssssss ) or ( same optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("parameters optimization algorithmssssssssss") or ("same optimization algorithms"))*.
