Perhaps you should try some spelling variations:
"modified parameter optimized algorithmss" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization algorithmss"
"modified parameter estimation algorithm" » "modified parameter estimates algorithm", "modified parameter optimization algorithm"

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 optimized algorithmss") OR ("modified parameter estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter optimized algorithmss\") OR (\"modified parameter estimation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified parameter optimized algorithmss ) OR ( modified parameter estimation algorithm ))*.
