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