Perhaps you should try some spelling variations:
prediction algorithm » predation algorithm, predators algorithm
objective optimized » objective optimal, objective optimization
optimized algorithm » optimized algorithms, optimizer algorithms
a prediction » _ prediction, a predictive, a predictor
modified a » modified _, modified df, modified adam

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 prediction algorithm ) OR ( modified objective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified a prediction algorithm ) or ( modified objective optimized algorithm ))*.
