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 one algorithm" » "model using our algorithm", "model using _ algorithm", "model using mom algorithm", "code using one algorithm", "models nursing one algorithm", "powder using one algorithm", "model using open algorithm", "model using pre algorithm", "model using online 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 one algorithm") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( model using one algorithm ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using one algorithm") or ("modified multiobjective optimization algorithm"))*.
