Perhaps you should try some spelling variations:
"parameters optimisation algorithmssssssssssss" » "parameter optimization algorithmssssssssssss", "parameter estimation algorithmssssssssssss", "parameters optimization algorithmsssssssssssss", "parameters estimation algorithmssssssssssss", "parameters estimation algorithmsssssssssssss"
"parameter optimisation algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameter optimization algorithms", "parameter estimation algorithms"

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 optimisation algorithmssssssssssss") OR ("parameter optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( parameters optimisation algorithmssssssssssss ) or ( parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("parameters optimisation algorithmssssssssssss") or ("parameter optimisation algorithm"))*.
