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: "((\"model using egarch algorithm\") OR (\"modified multiobjective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( model using egarch algorithm ) OR ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using egarch algorithm") OR ("modified multiobjective optimization algorithm"))*.
