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