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