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

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