Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"tower forecasting method algorithm" » "tower focusing method algorithm", "tower forecasting mixed algorithm", "tower forecasting mom algorithm", "power forecasting method algorithm", "lower 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: (("tower forecasting method algorithm") or ("modified notion approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("tower forecasting method algorithm") OR ("modified notion approximation algorithms"))*.
• Removing quotes may allow a broader search: (( tower forecasting method algorithm ) or ( modified notion approximation algorithms ))*.
