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

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

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