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

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