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

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