Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters optimized algorithms", "modified parameter optimization algorithms", "modified parameter estimation algorithms"
"designed network estimation algorithms" » "designed network estimation algorithm", "designed network optimisation algorithm", "designed network approximation algorithms", "designed network optimization algorithms", "defined network estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("designed network estimation algorithms") OR ("modified parameters optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"designed network estimation algorithms\") OR (\"modified parameters optimization algorithms\"))".
• Removing quotes may allow a broader search: (( designed network estimation algorithms ) OR ( modified parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("designed network estimation algorithms") OR ("modified parameters optimization algorithms"))*.
