Perhaps you should try some spelling variations:
"modified df prediction algorithm" » "modified df predation algorithm", "modified df predators algorithm", "modified _ prediction algorithm", "modified a prediction algorithm", "modified admet prediction algorithm", "modified adam prediction algorithm", "modified bi1 prediction algorithm"
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective solution algorithm", "modified objective convolution algorithms"

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