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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("core using pre algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("core using pre algorithm") OR ("modified multiobjective optimized algorithm")).
• Removing quotes may allow a broader search: (( core using pre algorithm ) or ( modified multiobjective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("core using pre algorithm") or ("modified multiobjective optimized algorithm"))*.
