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 algorithmssssssssssssssss" » "same optimization algorithmsssssssssssssssss", "same optimisation algorithmssssssssssssssss", "same estimation algorithmssssssssssssssss", "game optimization algorithmssssssssssssssss", "stage optimization algorithmssssssssssssssss", "qoe optimization algorithmssssssssssssssss"

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