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