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