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

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

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