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 algorithmssssssssssssss" » "same optimization algorithmsssssssssssssss", "same optimisation algorithmssssssssssssss", "same estimation algorithmssssssssssssss", "game optimization algorithmssssssssssssss", "stage optimization algorithmssssssssssssss", "qoe optimization algorithmssssssssssssss"

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