Perhaps you should try some spelling variations:
"attributed estimation algorithmssss" » "attributed estimation algorithm", "attribute optimization algorithmssss", "attributed estimation algorithmsss", "attributed optimization algorithmssss", "attributed optimisation algorithmsss"
"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: "((\"attributed estimation algorithmssss\") OR (\"parameters estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( attributed estimation algorithmssss ) OR ( parameters estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("attributed estimation algorithmssss") OR ("parameters estimation algorithms"))*.
