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: (("model using morse algorithm") OR ("modified multiobjective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using morse algorithm\") OR (\"modified multiobjective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( model using morse algorithm ) OR ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("model using morse algorithm") OR ("modified multiobjective optimization algorithms"))*.
