Perhaps you should try some spelling variations:
"attributed optimization algorithm" » "attribute optimization algorithm", "attributed optimization algorithms", "attributed optimisation algorithm", "attributed estimation algorithm"
"parameters optimization algorithmssssssssss" » "parameter optimization algorithmssssssssss", "parameter estimation algorithmssssssssss", "parameters optimization algorithmsssssssssss", "parameters optimisation algorithmssssssssss", "parameters estimation algorithmssssssssss"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("attributed optimization algorithm") OR ("parameters optimization algorithmssssssssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"attributed optimization algorithm\") OR (\"parameters optimization algorithmssssssssss\"))".
• Removing quotes may allow a broader search: (( attributed optimization algorithm ) OR ( parameters optimization algorithmssssssssss )).
• Adding a wildcard symbol may retrieve word variants: (("attributed optimization algorithm") OR ("parameters optimization algorithmssssssssss"))*.
