Perhaps you should try some spelling variations:
"modified one approximation algorithm" » "modified one approximation algorithms", "modified time approximation algorithm", "modified _ approximation algorithm", "modified rough approximations algorithm", "modified male approximation algorithm", "modified near approximation algorithm", "modified orca approximation algorithm"
"modified a prediction algorithm" » "modified a predation algorithm", "modified a predators algorithm", "modified _ prediction algorithm", "modified a predictive algorithm", "modified a predictor algorithm", "modified df prediction algorithm", "modified adam prediction 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 a prediction algorithm") or ("modified one approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified a prediction algorithm") OR ("modified one approximation algorithm")).
• Removing quotes may allow a broader search: (( modified a prediction algorithm ) or ( modified one approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified a prediction algorithm") or ("modified one approximation algorithm"))*.
