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 our algorithm" » "mapping forecasting air algorithm", "mapping forecasting _ algorithm", "mapping forecasting source 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 optimization algorithm\") OR (\"mapping forecasting our algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( mapping forecasting our algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("mapping forecasting our algorithm"))*.
