Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"model using morse algorithm" » "model using source algorithm", "model using mom algorithm", "code using morse algorithm", "models nursing morse algorithm", "powder using morse algorithm", "model using force algorithm"

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

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