Perhaps you should try some spelling variations:
"model forecasting method algorithm" » "model focusing method algorithm", "model forecasting mixed algorithm", "model forecasting mom algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca 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 one approximation algorithms") OR ("model forecasting method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified one approximation algorithms\") OR (\"model forecasting method algorithm\"))".
• Removing quotes may allow a broader search: (( modified one approximation algorithms ) OR ( model forecasting method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithms") OR ("model forecasting method algorithm"))*.
