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

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

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