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

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: (("same optimization algorithmssssssssssssss") OR ("parameter optimization algorithms"))~.
• Removing quotes may allow a broader search: (( same optimization algorithmssssssssssssss ) or ( parameter optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("same optimization algorithmssssssssssssss") or ("parameter optimization algorithms"))*.
