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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameters estimation algorithmssssss") OR ("attributed estimation algorithms"))~.
• Removing quotes may allow a broader search: (( parameters estimation algorithmssssss ) or ( attributed estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("parameters estimation algorithmssssss") or ("attributed estimation algorithms"))*.
