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 parameter optimized algorithms" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter 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: (("modified network estimation algorithms") OR ("modified parameter optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified network estimation algorithms\") OR (\"modified parameter optimized algorithms\"))".
• Removing quotes may allow a broader search: (( modified network estimation algorithms ) OR ( modified parameter optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified network estimation algorithms") OR ("modified parameter optimized algorithms"))*.
