Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"mapping forecasting method algorithm" » "mapping focusing method algorithm", "mapping forecasting mixed algorithm", "mapping forecasting mom algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping forecasting method algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping forecasting method algorithm") OR ("modified multiobjective optimization algorithm"))*.
• Removing quotes may allow a broader search: (( mapping forecasting method algorithm ) or ( modified multiobjective optimization algorithm ))*.
