Perhaps you should try some spelling variations:
"attributed estimation algorithmssss" » "attributed estimation algorithm", "attributed estimation algorithmsss", "attributed optimization algorithmssss", "attributed optimisation algorithmsss", "attribute optimization algorithmssss"
"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.

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