Perhaps you should try some spelling variations:
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms"
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters approximation 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 parameter optimisation algorithm") OR ("modified parameters estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter optimisation algorithm\") OR (\"modified parameters estimation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithm ) OR ( modified parameters estimation algorithms ))*.
