Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"code using mental algorithm" » "code using genetic algorithm", "code using control algorithm", "code using mppt algorithm", "code using metal algorithm", "code nursing mental algorithm", "code using medical algorithm", "core using mental 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: (("code using mental algorithm") OR ("modified multiobjective optimization algorithms"))~.
• Removing quotes may allow a broader search: (( code using mental algorithm ) or ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("code using mental algorithm") or ("modified multiobjective optimization algorithms"))*.
