Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"model using egarch algorithm" » "model using search algorithm", "model using source algorithm", "code using egarch algorithm", "models nursing egarch algorithm", "powder using egarch 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 (\"model using egarch algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( model using egarch algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("model using egarch algorithm"))*.
