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 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"

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 algorithm") OR ("model using ibm algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"model using ibm algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( model using ibm algorithm ))*.
