Perhaps you should try some spelling variations:
"parameter optimisation algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameter optimization algorithms", "parameter estimation algorithms"
"same optimisation algorithmssssssssss" » "same optimization algorithmsssssssssss", "same estimation algorithmssssssssss", "same estimation algorithmsssssssssss", "game optimization algorithmssssssssss", "stage optimization algorithmssssssssss", "_ optimisation 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 algorithm") OR ("same optimisation algorithmssssssssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"parameter optimisation algorithm\") OR (\"same optimisation algorithmssssssssss\"))".
• Removing quotes may allow a broader search: (( parameter optimisation algorithm ) OR ( same optimisation algorithmssssssssss )).
• Adding a wildcard symbol may retrieve word variants: (("parameter optimisation algorithm") OR ("same optimisation algorithmssssssssss"))*.
