Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer 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"

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