Perhaps you should try some spelling variations:
"modified dfllocation optimisation algorithm" » "modified allocation optimization algorithm", "modified dfllocation optimization algorithms", "modified dfllocation estimation algorithm", "modified dfllocation estimation algorithms"
"modified a predictor algorithm" » "modified a predators algorithm", "modified a predation algorithm", "modified _ predictor algorithm", "modified a prediction algorithm", "modified _ prediction algorithm", "modified df predictor algorithm", "modified adam predictor 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 predictor algorithm") OR ("modified dfllocation optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified a predictor algorithm ) or ( modified dfllocation optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified a predictor algorithm") or ("modified dfllocation optimisation algorithm"))*.
