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