Perhaps you should try some spelling variations:
"machinery forecasting method algorithm" » "mapping forecasting method algorithm", "machinery focusing method algorithm", "machinery forecasting mixed algorithm", "machinery forecasting mom algorithm"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("machinery forecasting method algorithm") OR ("modified objective estimation algorithm"))~.
• Removing quotes may allow a broader search: (( machinery forecasting method algorithm ) or ( modified objective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("machinery forecasting method algorithm") or ("modified objective estimation algorithm"))*.
