Perhaps you should try some spelling variations:
"modified a predictive algorithm" » "modified a predation algorithm", "modified a predators algorithm", "modified _ predictive algorithm", "modified _ predicting algorithm", "modified _ prediction algorithm", "modified df predictive algorithm", "modified adam predictive algorithm"
"modified time approximation algorithms" » "modified one approximation algorithms", "modified _ approximation algorithms", "modified bi1 approximation algorithms", "modified male approximation algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified time approximation algorithms") OR ("modified a predictive algorithm"))~.
• Removing quotes may allow a broader search: (( modified time approximation algorithms ) or ( modified a predictive algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified time approximation algorithms") or ("modified a predictive algorithm"))*.
