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

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