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

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

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