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

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