Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"mapping forecasting air algorithm" » "mapping forecasting _ algorithm", "mapping forecasting mixed algorithm", "mapping forecasting our algorithm", "mapping forecasting adam algorithm", "mapping forecasting qspr algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective estimation algorithm\") OR (\"mapping forecasting air algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) OR ( mapping forecasting air algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") OR ("mapping forecasting air algorithm"))*.
