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 mppt algorithm" » "mapping forecasting mixed algorithm", "mapping forecasting _ algorithm", "mapping forecasting air algorithm", "mapping forecasting mom algorithm", "mapping forecasting qspr algorithm"

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

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