Perhaps you should try some spelling variations:
"mapping forecasting method algorithm" » "mapping focusing method algorithm", "mapping forecasting mixed algorithm", "mapping forecasting mom algorithm"
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation algorithms"

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: (("mapping forecasting method algorithm") OR ("modified network approximation algorithms"))~.
• Removing quotes may allow a broader search: (( mapping forecasting method algorithm ) or ( modified network approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("mapping forecasting method algorithm") or ("modified network approximation algorithms"))*.
