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

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 optimization algorithms") OR ("parameters optimization algorithmssssssss"))~.
• Removing quotes may allow a broader search: (( attributed optimization algorithms ) or ( parameters optimization algorithmssssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("attributed optimization algorithms") or ("parameters optimization algorithmssssssss"))*.
