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

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

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