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