Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"model using pre algorithm" » "model using mppt algorithm", "model using qspr algorithm", "model using _ algorithm", "code using pre algorithm", "models nursing pre algorithm", "powder using pre algorithm", "model nursing pre algorithm", "model using one algorithm", "model using ph algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using pre algorithm\") OR (\"modified multiobjective optimizer algorithms\"))~".
• Removing quotes may allow a broader search: (( model using pre algorithm ) OR ( modified multiobjective optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using pre algorithm") OR ("modified multiobjective optimizer algorithms"))*.
