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

• Performing a fuzzy search may retrieve terms with similar spellings: (("same optimization algorithmssssssssssssssss") OR ("parameter optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"same optimization algorithmssssssssssssssss\") OR (\"parameter optimization algorithms\"))".
• Removing quotes may allow a broader search: (( same optimization algorithmssssssssssssssss ) OR ( parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("same optimization algorithmssssssssssssssss") OR ("parameter optimization algorithms"))*.
