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