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