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

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"parameter optimisation algorithm\") OR (\"parameter optimisation algorithmssssssssssss\"))~".
• Removing quotes may allow a broader search: (( parameter optimisation algorithm ) OR ( parameter optimisation algorithmssssssssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("parameter optimisation algorithm") OR ("parameter optimisation algorithmssssssssssss"))*.
