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