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