Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"model using force algorithm" » "model using source algorithm", "model using search algorithm", "code using force algorithm", "models nursing force algorithm", "powder using force algorithm", "model using morse algorithm", "model cutting force 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 optimisation algorithm") or ("model using force algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimisation algorithm") OR ("model using force algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( model using force algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("model using force algorithm"))*.
