Perhaps you should try some spelling variations:
"designed network approximation algorithm" » "designed network approximation algorithms", "defined network approximation algorithm"
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing 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 static optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"designed network approximation algorithm\") OR (\"modified static optimization algorithms\"))".
• Removing quotes may allow a broader search: (( designed network approximation algorithm ) OR ( modified static optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("designed network approximation algorithm") OR ("modified static optimization algorithms"))*.
