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 algorithmssssssssss" » "parameters optimisation algorithmsssssssss", "parameters estimation algorithmssssssssss", "parameters estimation algorithmsssssssss", "parameter optimization algorithmssssssssss", "parameter estimation algorithmssssssssss"

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