Perhaps you should try some spelling variations:
"same optimization algorithmssssssssssssss" » "same optimization algorithmsssssssssssssss", "same optimisation algorithmssssssssssssss", "same estimation algorithmssssssssssssss", "game optimization algorithmssssssssssssss", "stage optimization algorithmssssssssssssss", "qoe optimization algorithmssssssssssssss"
"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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"same optimization algorithmssssssssssssss\") OR (\"parameter optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( same optimization algorithmssssssssssssss ) OR ( parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("same optimization algorithmssssssssssssss") OR ("parameter optimization algorithm"))*.
