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

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 bayesian optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"designed network approximation algorithm\") OR (\"modified bayesian optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( designed network approximation algorithm ) OR ( modified bayesian optimization algorithm ))*.
