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