Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"core using mental algorithm" » "core using genetic algorithm", "core using control algorithm", "core using mppt algorithm", "core using metal algorithm", "core nursing mental algorithm", "core using medical algorithm", "code using mental algorithm", "care nursing mental 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 mental algorithm") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("core using mental algorithm") OR ("modified multiobjective optimization algorithms")).
• Removing quotes may allow a broader search: (( core using mental algorithm ) or ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("core using mental algorithm") or ("modified multiobjective optimization algorithms"))*.
