Perhaps you should try some spelling variations:
"modified quantile optimisation algorithms" » "modified quantile optimization algorithms", "modified quantile estimation algorithms", "modified quantile estimation algorithm", "modified quantile optimization algorithmss", "modified quantile estimation algorithmss", "modified adaptive optimisation algorithms"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified quantile optimisation algorithms") OR ("modified parameter optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified quantile optimisation algorithms\") OR (\"modified parameter optimisation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified quantile optimisation algorithms ) OR ( modified parameter optimisation algorithm ))*.
