Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"model using source algorithm" » "model using our algorithm", "model using search algorithm", "model using force algorithm", "model using morse algorithm", "code using source algorithm", "models nursing source algorithm", "powder using source algorithm"

You may be able to get more results by adjusting your search query.

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