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