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 algorithmssssssssssssssss" » "parameter optimization algorithmssssssssssssssss", "parameter estimation algorithmssssssssssssssss", "parameter optimization algorithmsssssssssssssssss", "parameter estimation algorithmsssssssssssssssss"

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