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