Perhaps you should try some spelling variations:
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation algorithm", "designed network optimization algorithm"
"modified model predicting algorithm" » "modified model predation algorithm", "modified model predators algorithm", "modified model splitting algorithm", "modified model predictive algorithm", "modified model reduction algorithm", "modified male predicting algorithm"

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

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