Perhaps you should try some spelling variations:
"modified model predictive algorithm" » "modified model predation algorithm", "modified model predators algorithm", "modified model reduction algorithm", "modified male predictive algorithm"
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"

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

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