Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"towler forecasting method algorithm" » "towler focusing method algorithm", "towler forecasting mixed algorithm", "towler forecasting mom algorithm", "tower forecasting method algorithm", "bowler forecasting method algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("towler forecasting method algorithm") OR ("modified notion approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"towler forecasting method algorithm\") OR (\"modified notion approximation algorithms\"))*".
• Removing quotes may allow a broader search: (( towler forecasting method algorithm ) OR ( modified notion approximation algorithms ))*.
