Perhaps you should try some spelling variations:
optimisation algorithmssss » optimisation algorithm, optimization algorithms
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
parameter optimisation » parameter optimization, parameter estimation
attribute » attributed, attributes

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( attribute optimization algorithm ) or ( parameter optimisation algorithmssss ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( attribute optimization algorithm ) OR ( parameter optimisation algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (( attribute optimization algorithm ) or ( parameter optimisation algorithmssss ))*.
