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