Perhaps you should try some spelling variations:
"same optimization algorithmssssss" » "same optimisation algorithm", "same optimisation algorithmsssss", "same estimation algorithmssssss", "same estimation algorithmsssss", "game optimization algorithmssssss", "stage optimization algorithmssssss", "qoe optimization algorithmssssss"
"parameters optimization algorithms" » "parameter optimization algorithms", "parameter estimation algorithms", "parameters optimisation algorithm", "parameters estimation algorithms", "parameters estimation 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 algorithmssssss\") OR (\"parameters optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( same optimization algorithmssssss ) OR ( parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("same optimization algorithmssssss") OR ("parameters optimization algorithms"))*.
