Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"machinery forecasting method algorithm" » "mapping forecasting method algorithm", "machinery focusing method algorithm", "machinery forecasting mixed algorithm", "machinery forecasting mom 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: (("modified multiobjective estimation algorithm") OR ("machinery forecasting method algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( machinery forecasting method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("machinery forecasting method algorithm"))*.
