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 algorithmsssssssss" » "parameter optimization algorithmsssssssss", "parameter estimation algorithmsssssssss", "parameter optimization algorithmssssssssss", "parameter estimation algorithmssssssssss"

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

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