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 ibm algorithm" » "model using mom algorithm", "model using adam algorithm", "model using _ algorithm", "code using ibm algorithm", "models nursing ibm algorithm", "powder using ibm algorithm", "model using rbf algorithm"

Try widening your search to All Fields.

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