Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified df predictive algorithm" » "modified df predation algorithm", "modified df predators algorithm", "modified _ predictive algorithm", "modified a predictive algorithm", "modified model predictive algorithm", "modified adam predictive algorithm", "modified bi1 predictive 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 df predictive algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df predictive algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( modified df predictive algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df predictive algorithm") or ("modified notion optimization algorithms"))*.
