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"
"mapping learning prediction algorithm" » "mapping learning predation algorithm", "mapping learning predators algorithm", "machine learning prediction algorithm", "enabling learning prediction algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping learning prediction algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping learning prediction algorithm") OR ("modified notion optimization algorithms"))*.
• Removing quotes may allow a broader search: (( mapping learning prediction algorithm ) or ( modified notion optimization algorithms ))*.
