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

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 algorithmssssssss") OR ("parameters estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"attributed optimization algorithmssssssss\") OR (\"parameters estimation algorithms\"))".
• Removing quotes may allow a broader search: (( attributed optimization algorithmssssssss ) OR ( parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("attributed optimization algorithmssssssss") OR ("parameters estimation algorithms"))*.
