Perhaps you should try some spelling variations:
"modified response optimisation algorithm" » "modified response optimization algorithms", "modified response estimation algorithm", "modified response estimation algorithms", "modified response optimization algorithm"
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation 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: "((\"modified response optimisation algorithm\") OR (\"modified network approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified response optimisation algorithm ) OR ( modified network approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified response optimisation algorithm") OR ("modified network approximation algorithms"))*.
