Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimisation algorithms", "modified notion estimation algorithmss", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"certified network optimization algorithm" » "certified network optimisation algorithm", "certified network estimation algorithm", "certified network estimation algorithms", "verified network optimization algorithm"

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

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