Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("model using egarch algorithm") or ("modified multiobjective estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("model using egarch algorithm") OR ("modified multiobjective estimation algorithms")).
• Removing quotes may allow a broader search: (( model using egarch algorithm ) or ( modified multiobjective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("model using egarch algorithm") or ("modified multiobjective estimation algorithms"))*.
