Perhaps you should try some spelling variations:
"machines forecasting method algorithm" » "mapping forecasting method algorithm", "machines focusing method algorithm", "machines forecasting mixed algorithm", "machines 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machines forecasting method algorithm\") OR (\"modified one approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( machines forecasting method algorithm ) OR ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("machines forecasting method algorithm") OR ("modified one approximation algorithms"))*.
