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"
"attributes optimisation algorithms" » "attribute optimization algorithms", "attributes optimization algorithms", "attributes estimation algorithms", "attributes estimation algorithm", "attributes optimization algorithmss", "attributes estimation algorithmss"

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