Perhaps you should try some spelling variations:
"mapping forecasting mixed algorithm" » "mapping forecasting method algorithm", "mapping forecasting air algorithm", "mapping forecasting driven algorithm", "mapping forecasting winner 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping forecasting mixed algorithm") or ("modified network approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping forecasting mixed algorithm") OR ("modified network approximation algorithms")).
• Removing quotes may allow a broader search: (( mapping forecasting mixed algorithm ) or ( modified network approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("mapping forecasting mixed algorithm") or ("modified network approximation algorithms"))*.
