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