Perhaps you should try some spelling variations:
"modified dfllocation optimization algorithm" » "modified allocation optimization algorithm", "modified dfllocation optimization algorithms", "modified dfllocation optimisation algorithm", "modified dfllocation estimation algorithm"
"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"

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 a predictive algorithm") OR ("modified dfllocation optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified a predictive algorithm ) or ( modified dfllocation optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified a predictive algorithm") or ("modified dfllocation optimization algorithm"))*.
