Perhaps you should try some spelling variations:
"modified quantile approximation algorithms" » "modified time approximation algorithms", "modified diophantine approximation algorithms", "modified adaptive approximation algorithms"
"modified carbon optimization algorithm" » "modified carbon optimization algorithms", "modified carbon optimisation algorithm", "modified carbon estimation algorithm", "modified market optimization algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified quantile approximation algorithms") or ("modified carbon optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quantile approximation algorithms") OR ("modified carbon optimization algorithm")).
• Removing quotes may allow a broader search: (( modified quantile approximation algorithms ) or ( modified carbon optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified quantile approximation algorithms") or ("modified carbon optimization algorithm"))*.
